Can you send pictures? Not eating is usually normal shortly after getting them, but you told me that it has been 3 months. It’s also normal for cories not to eat in front of you, and even if the food broke down, they use their barbels and sift sand to filter any edible particles to eat. Are their sides caved in? Emaciated? Make sure to acclimate the new ones properly and trust me, unless they genuinely sick, they will appreciate the company. Corydoras are extremely social creatures.
Cory Laying On Side And Then Swimming Normally With Others

Good. Cories don’t usually starve (especially when you are target feeding them) unless they are being outcompeted, sick, or their mouth/barbels are compromised. So don’t worry too much.
Just regularly keep an eye and do your water tests before water changes.

Here is a picture of my tank the pleco one of the pepper cory cats acting noraml swimming around and one of the panda corys hiding under the rockAttachments
It’s a bit hard to tell, but they are not pale. (Well, not pale enough to seem sick)
That tank is definitely too barren for them.
Hopefully they will get used to you. The corydoras I have purchased rarely got used to me, and when they did it took a year.
The ones I have bred and raised from birth however, are unfazed by human activity. Maybe after you get them some friends, you can breed them. It’s very easy, educational, and one of the most wonderful things to witness.

I would return the albinos and increase the peppered and pandas as el337 suggested. While technically your tank would probably be big enough for 3 schools of cories, I always recommend making schools as large as you can. I made the same mistake at first and had sterbai, emerald and peppered in my tank. They didn't shoal together and about half hid most of the time. Now I have 8 of the same species and the difference is amazing. They're so energetic and swim around everywhere.

But, I didn't see any T-ing or whatever the proper term is, so now I'm a little concerned something else may be going on.
Of note: I moved ab 2 cups of my sand substrate from under a big piece of driftwood in corner to build up around my plants as substrate was getting low around them just yesterday. So it's like new sand in area they're doing this.

Upon watching her further, it looks like she may have an injury to her right ventral fin. It looks like she's not using it and poor thing looks full of eggs.This would explain her falling over to one side and then righting herself. If this is what's going on, I don't think it's bad, but what can I do for her? Melafix or let it be?

She started it again today after a 40% WC. It seems to be part of her spawning behavior although I'm not seeing it linked to that. Also she's as big as a house, and when she goes to lay her eggs, she's not letting go of her eggos. But she's going thru the motions as if she thinks she is. Does that make any sense?
Is their a chance she's gravid? I have 7 panda cory's and believe 2 are female.
(Last spawning one of the females only laid a few eggs in the corners of the tank, up and down each side, my Angel ate all of them) I've got a video from today I'll upload in a minute.

New substrate a couple of months back, changed from white to black sand. Added a piece of driftwood about a month ago. New plants but that was after the cory was flashing. Hooked my UV filter back up a few days ago.
I'm stumped. The only thing that stands out was this filmy residue on sides of tank. Not algae. I cleaned all inside walls of my tank last night. The only reason I hadn't being my Angelfish freaks out when she can see herself in the 2 sidewalls and will just swim up and down, up and down trying to fight herself if they are too clean. lol
Also food wise, I'm always adding new foods to vary up their diet. Recently, Frozen Super Brine Shrimp, HikarI Crab Cuisine, Fluval Bug Bites.

When did the filmy residue appear? How did you clean it off?
I'm out of my depth here, but if there's nothing wrong with the water then I'd be inclined to suspect a parasite of some kind. I've read that parasites can take a while to cause observable symptoms, so it _could_ have been something that came in on the driftwood? I'm grasping at straws here.
Maybe it would be worth running a complete set of water parameter tests on the tank water and on your source water? If there's any significant difference, then maybe there's something in the tank that is shifting the hardness or pH and therefore causing a period of adjustment every time you do a water change?

I had some of my cories flashing and stressing, I did another water test to find my nitrites had gone up to 1ppm. Everything else was normal. I started doing small water changes every other day, and placing a small dose of seachem prime in the water in order to detoxify the nitrites until they went down. Since then none of my cories have flashed.
I would also make sure there are no signs of ich, though it can be harder to see on a cory catfish.

HI - just correct me if I am wrong, but the films seem to indicate a very strong water current to the right-hand side of the tank. Is that where the sponge filter is? Where is the AquaCLear 70 located?
The other thing is, when and how did last clean the filters? i.e. do you clean both at the same time, what do you use to clean the filters?

so in an earlier thread, i mentioned that my water was cloudy, my Ph dropped for some reason, and my cories where acting weird, well, despite water changes, water is still cloudy, and today i found one of my cories lying on it's side, looking very dead, but it's NOT dead, it moved. I have no idea what's going on here.

how old is the setup? is it cycled? what are your water parameters? cloudy is usually BB building up.

when ph drops below 6.5 the ammonia becomes ammonium and doesn't help the BB stay alive, as the BB needs ammonia. with the low ph the BB starts to die off, after you do a W/C the tap water ph is high enough to raise it out of ammonium back to ammonia, but your BB is low and weak, which is why it has gone cloudy "Bacteria Bloom" but then it drops after 24hrs back below the 6.5ph which then stops the ammonia feeding the BB and the BB starts to die off again. Regardless what people say about the ph lvls it should always be above 6.8ph. My tap is 7.5ph but after 24hrs it drops to 6.5ph. DO NOT USE chems to control ph, use crushed coral in your filter if you have room or put in a media bag and place in back corner of your tank by the intake. 1cup CC to 30g if inside filter or 2cups CC to 20g if placed in media bag under intake. Monitor every 24hrs as thats how long it usualy takes to have a big change in your tank. Monitor for a few days every 24hrs till you get the proper ph of 7 or 7.5.
Your problem lies in the ph lvl. CC will raise the ph slowly enough not to harm the fish. its best to have a stabloe ph and not fluctuate to much, but when it gets below 6.5 you have a chance of crashing your cycle (which is where you are almost at) and thats not going to feed your BB and itll die off which is where things are loking like they are now. Get some Crushed Coral

There's no ammonia cause its now ammonium. Cause its below 6.5. When you do a wc the ph lvl rises for the day turning the ammonium back to ammonia. Your bb isn't strong enough to catch it and chances are your lil guy got ammonia poisoning. The hrs later it goes back to 6.5 turning the ammonia back to ammonium. Your lil guy died from ammonia poisoning or the stress from the fluctuation of the ph lvl going up and down to fast
I was in the same spot when I started and learned about the ph lvl from my LFS. Stress is bad on lil fishies. You need to maintain a proper ph lvl

Because it is likely your tank is not fully cycled and there is a good chance a ammonia or nitrite spike is what likely killed the Cory and the Cloudy water points to that as well do to being a bacteria bloom.

How old is the tank set up and what do you use to test you water parameters
as i already stated in one of the replies, I TESTED THE WATER, and there is NO AMMONIA OR NITRITE, AND ONLY AROUND 2 NITRATE. please actually read the thread before assuming I don't know how to cycle a tank.
Firstly, API test kits read ammonium as ammonia, so i am 100% certain there is none of either. Also ammonium, unlike ammonia, is harmless. Also my ph actually goes DOWN when i do a water change, as i have a Ph buffer in the tank, which is still there, so I'm confused as to why my Ph buffer isn't working.
I tested the water a few hours before the cory died, so even if DOUBLED the amount of food, it WOULD NOT BE POSSIBLE for an ammonia spike to kill the cory.

Im sorry if I offended you. I think what myself and others are implying is that your tank is not fully cycled, which would make sense as to why your nitrates may be so low.
As others stated your low ph could cause your cycle to stall and when that happened there may have been a build up. You stated you were changing water due to cloudiness(which a few of us said could be a bacteria bloom) by doing that it may have raised your PH enough to get the the bacteria going again to level things out.
I did read your post, and the following responses after and I added to that to try to give some
Input.
I have no idea what else it could have been, good luck!
I changed the water a few days ago, also my tape water is lower ph than the tank water, so there is no reason for the tap water to cause bacteria bloom
It's kind of the middle if the night, but I'll test the tank tomorrow morning, and i guarantee you there will be no ammonia or nitrite.
