All Cory tanks

[KribensisLover1]

hello!

Does anybody have a tank with different schools of Cories? I have a 26 gallon and am interested to see if there’s any movemenrt above the bottom and also what types you have together and your experiences. And pics are great!!!!!!!!

I don't have one right now but I used to have pandas and albino/bronzes in a 50g. They mostly stuck to their own schools and never bothered or even interacted with the other school

Ok so was it cool? I mean Cories are great but was there a lot of tank activity or mainly floor activity with some zipping up to the top on occasion? I can’t decide if a Cory tank is awesome or boring (and I should instead do like 12 of one type and then a top swimming fish).

Cories by themselves just stay at the bottom... With the exception of Pygmy Cories which are all over the place. There was a lot of floor activity but the mid-top water column was all other fish.

I think it would probably be better to include another species that is temperature compatible with your cories and will occupy higher tank levels.

A possible alternative idea could be to just fill the tank about half way and plant some interesting plants that could grow emersed, with just the cories below?

The issue is it’s an acrylic tank with bracing so there are two small openings but not an open top at all. That’s a cool idea!!
Ok so basically back to the drawing board!!

Mmm OK, but if the tank is only half full the plants could at least grow out of the water to the top? I mean plants that are rooted in the substrate, so are growing partly under water but emerging above water level (leaving some open space for the Cories), I don't know how feasible this is, it was just an idea, I haven't ever tried this myself...

What do you think of chili rasboras? I am looking for fish that will pop on black on black back and substrates.

They are very pretty, but I don't have any experience with them, I would have to research their requirements as regards temperature, water parameters and hardiness...

What about looking at some tetras that occur naturally in the same region as the Corydoras you have?

That’s. Wonderful idea!! I was considering moving the Cory’s bc they are so camouflaged but your idea is wonderful and it didn’t even occur to me I am ashamed to admit!

 

[TClare]

What about serpae tetras? They are colourful and have a very wide distribution including the river systems where your Cories are found, I think,they will be less demanding than cardinals. What are the dimensions of your tank?

I have entertained the idea of chili rasboras, but I ended up going with ember tetras nano, mainly because they are hardier. They are a fun bunch that enjoy the upper and middle areas with a nice pop of color. I also wanted emerald danios. Both of these work great with dark backgrounds.

I have Pygmy, Similis, and Bronze Corydoras in a 29g planted tank, my Similis pick and choose if they want to school with the Bronzes or the pygmies. But most of the time my Similis stay in their group under all of my background and mid ground plants, my bronzes love the front open areas of my tank, and my pygmies school and rest on my hardscape in the middle and lower level of my tank, sometimes schooling with my ember tetras nanos just being playful or curious.

 

[Cyberfish]

I find pygmy corydoras and neon tetras do really well together. Sometimes they'll even swim in 1 big school.

I would love them but they’re weaker than cardinal tetras

 

[TClare]

Ember tetas would be nice, but you would need keep them at the lower end of their preferred temperature and the Corydoras (Hoplisoma actually) would be at their top temperature limit. so not an ideal situation.

I did look up chili rasboras, but it seems they. are just as delicate, or more so than cardinal tetras...

A couple of other possibilities - Bloodfin tetra -from the same region as the cories and can live in a wide range of temperatures, so would be happy at the lower temperatures preferred by the cories. I haven't kept them myself, but it seems like they are quite hardy, and with their silver colour and striking red fins they should show up well against the dark substrate.

Black neon tetras - also from the same region, they need to be kept a little warmer than the bloodfins, but still within the cories preferred range. Not so colorful but could still look good over the dark sand.

All of thiese will prefer soft water if possible, and be careful about changing too much water at once if it s very different to the tank water. But I think they are not as sensitive as the cardinal tetras.

Cardinals work well too. Often, neons are fine if you get them from a good LFS and keep good water parameters.

You can still find chilis??? I've looked everywhere and NOBODY has them anymore

No, I didn't try to find them, I just looked for information on them... the OP has had issues with cardinals and would like something less sensitive..also a species that would be more tempertaure compatible with the Hoplisoma species she has, cardinals need to be much warmer...

 

[KribensisLover1]

Not that big sadly. It’s 36 by 10–12 by 16
It’s a flatback hex 26 gallon and like 4–5” substrate so less water volume than that. And I have kept larger cool fish in there but I would like a schooling fish where I can get as many as possible. But I love the idea of (duh) actually matching regions.

 

[TClare]

Is the tank planted? Most schooling (or shoaling) fish would prefer some areas of dense planting but you also need to keep some open areas for the cories. Anyway check out the bloodfin or black neon tetras, maybe serpae are a bit big for a large group, bloodfins are quite long but slim, the tank is not too bad in length for them.

Ok TClare Cyberfish
so a couple things; I really think I’m swapping the peppered out bc they’re so hidden.

I saw Pygmys ands they are sooooo tiny I was SHOCKED. Like the ones I saw were almost invisible like .25”. Is this always the case? Bf they sound cool!! And I had green neons in the past but they were soooooo skittish that I never saw them. Do you know if black neons are the same?
I will look into ember and blood fin!!

Yes it is! And it’s getting very lush now!! My main goal was plants so I got aquasoil which has started this whole debacle. Bc otherwise I wouldn’t have ph jumping around with tap so high and tank so low!! Blood fin are awesome! Would they show up well you think? And neons are some of my faves always. As long as they aren’t too skittish! Basically I want a large school of fish that pop but aren’t too individually interesting (so it’s a stunning bunch of schooling) with Cories to give the tank the interesting behavioes.

 

[TClare]

Ah yes I remember the aquasoil. I haven’t kept either bloodfins or black neons so it’s worth reading up about those I think either would show up well. I thought of those because of the temperature preferences of your Cories, but if you are thinking of changing them you’ll have to check requirements again. However I do think it’s possible that yours will hide less as they become more settled, and having some other fish in the tank may help with this. You could probably have a few Pygmy Cories as well, they are very small and won’t add much to the bioload, they are nice, and interesting but as a main species they probably wouldn’t show up too well.

Ok! And yes the Cories were being so active tonight. I thought of an all Cory tank bc they really came to life after the cardinals were go e

Also I tested my TDS and it’s 179 tap and 205 tank.

I believe that TDS suggests that your water is not soft but not very hard either, however it will be good to,have the hardness tests as well. I think the tank water is lower because the plants are using some minerals from the water.

Oh no the tank water is higher—but I add flourish daily so maybe that’s why? Sorry if I wrote that wrong. The tank is 205 the tap is the lower.

Yes, the flourish would increase it.
