That’s a guppy isn’t it? Is there an orange spot on it? That is so random! Lol The tank is great I know I sent you pm but I didn’t catch up about the tank yes as to new fish, I had my original fish, juvenile severum and my 4 hoplo catfish and two Raphael’s I put in, on to the new fish, I got my big boy severum who seems to like to bite(I sucked up all his babies because I thought they were two male Severums lol) so he hates me now, I got two green terrors, 3 blood parrots! I had to give my firemouth away because he was a jerk to all the fish except for the big severum. So that’s how I left it for a bit but I noticed my eel was not happy in my 40 gallon breeder so I asked around again if he would be ok and I figured he is pretty fast and made a bunch of hiding places and he has been in there for two or three weeks and he absolutely loves it and has grown even more, then I said well let’s see if my yellow hump Geophagus can hang with all of them? Well the whole bunch of them get along great no one picks on anyone. Might change because the Severums are doing the spawning thing and they took a fourth of the tank away from the other fish and I was like why are they being so mean??? I had just gotten back from Bermuda( that’s when I sucked all the eggs! So stupid) lol I never took down my 55 gallon because I just dreaded it but guess what?!?!?! I just happen to run across a ThaI silk flowerhorn! !! !$&:! I wanted less work! So now I have him and his name is Fred and I am totally in love!! I know I will have to upgrade his tank soon he is 7” now but I just don’t think it’s big enough! When I get a bigger tank I have to really put the 55 away I can’t have anymore tanks! It’s crazy! I did have 7 so I dropped 1 tank instead of 2! Sorry so long just a whole lot of info I wanted to share, I haven’t talked to you in forever! Lol Did you ever get any panda frys? I gave 23 of my baby corys to the LFS and kept 6. Not one of those frys died! I am still amazed at that!
 
Hey Nikki. I don’t think it’s a guppy. I think I have a thread on that fish. Going to put those new pics on it see if anyone can id it.
Did not get a pm. Going to friend you.
Got to put some pics up. Had those type of fish when I first started. Severus and geophagus. I don’t see them in the pet stores any more. Had mine in a 55 can only imagine how big they will get in your tank.
Never had a flowerhorn but have seen them. Will he be going into the big tank? Can he go in with the other fish?
Yeah 7 tanks are just to much. Still can’t figure out how I got this 5 gallon shrimp tank. (**** fry) .
Ended up putting the second batch of Cory’s in my 90 and got some blue rams to eat the eggs now. So haven’t seen any fry in the 30.
 
I can’t wait to find out what it is! He is cute whatever he/she is

The large male Severum is 10 to 12 inches and the female is probably 6 inches. This Severum was one of the workers fish who just hung out in one of the tanks forever and people in my area probably do t pay more than ten bux for a fish and I liked him because he was big and wasn’t scared of people so now he is mine

I was thinking about putting him Fred the flowerhorn in the big tank because he was in a much smaller tank with a lot of other fish before he was rescued by the owner that I bought him from and he did fine but it just scares me because they can kill everything in the tank if they decide too so I will just keep him in his own tank

I can’t figure out how I have this many tanks! It was like one Betta tank and now 7!!! So not right! Lol

I bet the corys are happy in there I lost both of my rams she laid eggs and then she died almost immediately and in the process of the spawning she beat the out of my male and I just couldn’t save him plus he ate all the fry before he died! If my corys lay eggs now they don’t have a chance because they live with an eel and a Golden Nugget pleco so I see eggs and then they are gone.

I have a tank with guppies that won’t stop having babies and now my two mollies that I thought were both females are having fry constantly. I really don’t know what I am going to do because I suck at sexing them and I just don’t want any live bearers! They won’t stop!!! Lol
 
My Severums guarding their eggs! This happened this morning. Lol IMG_0799.jpg

This is Fred my FlowerhornIMG_0800.jpgIMG_0801.jpg

I don’t even know how to friend people on here. Lol I think it’s totally different on the phone than on the laptop. I very rarely go on the laptop, all I know is the stuff that I can do on the phone.

Severums had 100 eggs hatch and fry swimming for 3 days! 86 ssinit you need a Severum or ten!!! Lol

Rather 1000 lol
 
That’s a lot of fry!!! Thanks but I’m going to pass on them. Really don’t think they’d fit in my thank. Wow what are you going to go with them??

Fred is cool!!!
 
Thank you Fred is such a great fish I love him so much! I have no idea what I will do with them, I really didn’t think they would make it this long in a community tank but both parents are protecting them like crazy. I will say it won’t happen again! Lol it upsets the whole tank.
 
OMG! My cory laid eggs!

BAEE4B84-2053-4C0C-9CEE-44F7CBEEADC4.jpeg
I have NO idea how to take care of them! I was out of town for 2 days and they missed a day of feeding... I was nervous about losing a fish, but I did NOT expect this!

How do I take care of them??? I know they’ll get eaten if I leave them in here. What do I do??? HELP ASAP

It is always so thrilling when it happens the first time. Now that it has started it will happen often so if they don't hatch this time you will have lots of chances to get it right.

All of my fish had a feast today. My corys lay soooooo many eggs. I have several adult females and it seems when one starts laying them they all do. Now I just scrape them off the glass to make it easier for all the fish to eat them. The assassin snails and Elbert the pleco get the ones that are harder for me to get to.
 
Interesting! I thought my angels had laid again but they weren’t guarding the leaf so maybe they were cory eggs.
 
WhenI first raised cory eggs I added a marina breeder box to the side of my 20 long with a piece of polyfill on the return so the fry didnt go over the falls when they finally hatched. Since then I have a dedicated 5.5 cory fry tank with a sponge filter and the same marina breeder box acting as an extra filter with the polyfill on the return.

My setup.

I have a layer of sand, java moss and a marimo moss ball, an aerator, and a heater.

Please give me recommendations.

That will work till they become a couple weeks old. Once you see them wiggling around crush a pellet or flake up super fine into a powder and feed them a couple times a day with some frequent WC's daily and you could be well on your way to new corys. Good luck keep us updated!!

thank you. Some of the eggs have white spots on them, are those the fungal ones I need to remove?

They don’t look fuzzy. They’re just spots.
 
I personally never removed any but the way I had mine in the marina breeder box it was always circulating fresh water so I just let them do their thing.
 
My first babies have officially hatched When should I feed them and what should I do from now on?
 
Fry update:

It has been two days since the first fry hatched, so I’m planning on starting feeding tomorrow. I am gradually removing the remaining eggs, I don’t wanna siphon out the babies though!
This is my setup. I have added some plant life and a terra-cotta pot for shelter, and I had extra developed filter media (I removed it from another tank because it’s being treated) so the bacteria will stay alive and to maintain ammonia and nitrite levels. The water is that color because of an alder cone, to help prevent infection and give healthy tannins to the fry. This is my first time, so suggestions are welcomed and appreciated!

Hey guys so I am writing this in a hurry

My corydoras laid eggs

How do I harvest them

Do I just pick them up and put them in a breeding tub

I have a breeding box I can put in the tank

It's a community tank so I am the only one that protects the eggs

How do I know when they are fertilized
 
pick them up by rolling then up the glass or leaf, or whatever suffice they are on. fertilized eggs are very tough, and non fertilized eggs sometimes just burst. non fertilized eggs also turn white after a few days of being laid.
or you can do it like this
 
Cory eggs are easy. I used a credit card lightly under them and up the glass. Most stuck to the card. Take a few more than you want to keep. And grow them out. Good luck!!

Congrats!!! It's always exciting! The parent cories & other fish will snack on them, If it's on a leaf, or decoration you can remove the entire object & place it in another bin. They are very sticky, it's time consuming to pick out one egg at a time if you have 30+ eggs. I've tried to hatch eggs many times & I fail, my eggs are always clear, and do not hatch (another story) So the fertilized eggs will appear cream colored, but watch out if they turn fuzzy remove them- they have fungused over.
 
If it’s already to late by the time read this to safe this lot of eggs?
Next time ,
A single sided razor blade is my preferred method. But a plastic card or even your finger can get 80% without busting them. The eggs are softer in the first few minutes but you need to remove them as soon as you can before everyone eats them .

I suggest use the same tank water in a separate container. An air stone is my choice. I have not used meth blue but suggest you only add a very small amount , from what I have heard.
They hatch in 4 days so you better be ready.

A cool water change and live food cultures are triggers to spawning.
 
I just went to the store. I have a small tub im going to raise the fry in. Im going to use a plastic card to take the glass ones off and the ones on the leaf I will take off through taking the leaf out. In the container im going to put an "established" moss ball, Indian Almond Leaves and Methenlyle Blue

Im also running an airstone, what intensity should i do it at.

Also they are still laying eggs as I type this. There are loads of them right now. Although ive only seen one batch get fertilized, (who knows maybe he fertilized more).

I know that you know its fertilized once they are tan brown ish. But is there any other way?

Also how much time do i give the male to fertilize the eggs.
UPDATE: The female look like she's done laying eggs. Im going to wait a little to see if the male fertlizes the eggs
 
I’d remove what you want. These guys when hatched usually grow. So just take what you want or you’ll be over loaded with corys. If you saw the male fertilize that those and what’s on the leaf. What type of cory? I used first bites as there first food. Bbs also works well.
 
Ok sounds good! They are Corydoras Aeneus. The female is albino and the male is Bronze/green. I was going the the Venezuelan Orange lazers but these two corys that bred, are "rescue" fish.

I'm going to be feeding them hikari first bites then move onto bbs

Does this sounds like a good setup:
A small little 0.5g tub with Methlyane Blue, Indian almond leaves, moss ball, and airstone.
They will later be moved to a 15g grow out tank.
Also does the little egg hatcher container need a heater? My room temp is currently 72 and I'll also put it in the warmer places I can find

The male fertilises the eggs in the tee position with the female minutes before she lays them.

There is no meth blue in the river that I am aware of?
I don’t use it myself.
I am very happy to use chemicals any day I just don’t see the need to add that poison to the water that will have fry. One day I may use it ?

I add old established moss and other plant material to the breeding box that is used. I add old dirty gravel, old ornaments, old leaf litter and moss etc hoping to add micro creatures ( Infusorea).

My breeding boxes have air pushing new warm tank water 24/7 . You will need to be removing and replacing water at a set routine of your choice.

To answer your question.
An air stone can be set to a minimum and still move the same water around and around. It will not need to be a strong flow IMO.

Ok sounds good! Where do you place the breeder box? I have a breeder box that holds has little micro tad little vent holes to let the tank water in. Should I use that? Or a fully closed container?
 
If the holes are small enough so the fry can’t swim through say roughly 2 mm / 0.079 inches or less then that sounds like a suitable breeding box. If you can get extra flow from the discharge of a hang on back filter that’s even better.
I would not use the fully closed container unless you have to. Or wish to use meth blue without dosing the whole tank?

I have a handful of these 2 litre / . 50 gallons hang on front breeding boxes by Marina. They are ok but stick out into the room a bit much and can be knocked easily. They are air driven.

Oh ok good to know. I'll be using the Marina Floating Breeder box. The holes seem to be small enough...hopefully. Yeah I wasn't do happy on the idea of adding methelyne blue. I'm for sure not adding it not. Just a moss ball, an airstone and indian almond leaves (mostly for infusoria not but evantually for tannins)
 
Quick question: can I substitute. Indian Almond Leaves for Methenlyle blue? Coradee you may be able to help in this :) (and anyone else of course!!)
Click to expand...
I use alder cones which have a similar effect so I don’t see why you couldn’t use Indian almond leaves

Oh ok good to know. I'll be using the Marina Floating Breeder box.

I don’t think I’ve seen that make but if that has slits in the sides or bottom then newly hatched cory fry are small enough to get through
 
Hey guys so I just got it done

I have a small little kitchen food container and with it Im running an air pump (no airstone cause it seems better without it for now but when I have to slow the rate in about two days i will add the airstone), some indian almond leaves, a moss ball that's seasoned/established and a pothos leaf (this pothos leaf sinked under the water and the corys layed there eggs on it). My room temp is currently about 71-72 degrees. Ill be doing water changes on it daily (small) until about 3-5 days in when they are going to hatch. About two days after they hatch, they will go in their 15g grow out tank!!
 
UPDATE: hey guys so its been almost 3 days (not quite but getting there) and good news and bad news. Good news is is that I had nearly 70-80 healthy fertilized eggs and a lot had little black spots on them. Bad news, fungus wiped them out only leaving 10-20 healthy ones. Im hoping these hatch but idk at this point

I know that corydoras lay eggs every week or two (and my corydoras are already showing signs lol) so I'm going to prepare for the next batch (since this batch I couldn't prepare for at all cause i didn't even know that they were going to breed)

This being said I think this is going to be the strategy.
Buy some RO water and put it in the bin
Then add my Indian Almond Leaves. This is going to lower my ph a lot more since i have a higher tap ph (alkaline) and a very high kh..

With this and turning up the water flow just a tad more, i think i should be able to stop fungus from growing.

Although im not going to be able to buy 27g of RO water for the grow out tank, so should i just drip acclimate the fry when i move them to the grow out tank (since the pH is significantly different?

Thanks guys!!
 
Why are you fussing with RO for the Aneus cories? They are spawning in your water and so you should simply use the same water that you use during water changes to create the grow out tank, and when the fry are moved in, just make sure the temp are the same.....dont worry about using RO. That's for the really finicky species of cories which the Aneus Bronze cories are not one of. Your cories will breed through almost all water condition so long as it's healthy abd clean and the eggs are huge in numbers. Use M. Blue to fight off the fungus in your hatch out container, provide good aeration and make sure temp are the same when you transfer. Use tank water for water change in the container. Or better yet get the breeder box that's either in the tank itself or has a connection of water from the tank flowing through like the fluval breeder box with the airtube or the cheap marina net breeder box which is only 4 dollars where I am. You'll be overwhelmed with these guys soon enough like I am overwhelmed with my Sterbais babies which are just as easy to breed so long as clean water and good food is provided.
 
Ok that’s why I use methylene blue. It prevents fungus. It’s only used on the eggs. Once hatched it’s just clean water. I use it on discus eggs. Lol no it doesn’t run natural in rivers. Funny thing is it works :). Yes corys will lay eggs again. On the next water change let the new water go in a little colder. That usually starts them. Again just take the eggs you can use. Unless your pet store will take some what will you do with 70 corys. For the fry I use one of these. The tank water runs through it.E309ED2A-2909-431F-8CD3-381C81E968D5.jpeg57AA7ECF-33F0-4C1A-8685-23D503BB4C22.jpeg

Don't feel bad! I was very excited a little after Christmas when I first witnessed mine laying eggs, I kept losing them to fungus. I tried the net above airstone, egg tumbler, container/air stone. Kept fungusing. Finally I added a few drops of peroxide and they stopped but also never hatched, eggs were clear.
It's a learning curve for sure, eh?

My only thing is is that I don't want to use chemicals unless it's the last option.

So i'm not actually going to do RO for my tank, but RO for the breeding container because then I will be able to successfully lower ph which will naturally prevent fungus.
 
Ok you have an ro unit already? I’ve never tried that. My tap water is fine. But if you have one use it :). And let us know how it goes .

No I don't have an Ro water system but I know where to get some Ro water for pretty cheap. I just need a little bit of the RO Water since this is only for the tub/

I'll let you guys know how it goes!!
 
UPDATE: GOOD NEWS

YESSS
My first fry has now hatched. Only a couple hours old. All the other eggs should hatch any time now. I have about 11 more healthy eggs.

At least i got something out of it lol.
 
Congratulations on your success. It is always so exciting when we see our first eggs and even more so when some actually hatch. :)

I found I lost fewer eggs to fungus once I stopped exposing the eggs to the air. I hold the hatchery under water as I collect the eggs to prevent exposing them to the air.

I use the little hatchery I made and Coradee graciously attached instructions to making one to her thread on raising cory fry. I keep the hatchery in the tank the parents are in and where the fry will go once big enough.

The holes in the hatchery allow fresh water to constantly flow through it but small enough not to allow the super tiny fry from getting through. BTW: I've not used MB although I did buy some at one point thinking I may one day need it. Although fresh water is going through the hatchery I still use my turkey baster to pull water out and allow a rush of fresh water to flow in at least once a day. This is to prevent taking a chance the water in the bottom of the hatchery isn't as fresh as it needs to be.
