Emerald Cories almost dead

I believe it was from cold temperatures, but here it goes: I had a single Cory in a 20 gallon tank with some platies. The tank was about 80ish degrees. I decided to get two more to make the minimum sized group. So I took out my original one, and floated it in a 55 gallon tank, along with the two new ones floating in their bags. They were left there for about an hour, then I came back and released them. That was last night. This morning I check them and I thought they were all dead. I check everyhting I can, and it turns out one of the heaters was no longer working. Then tank was at 71 degrees at the top. I quickly gathered all three and they are now floating in a bag in my 20 gallon tank. My original one is upside down. I am really worried. Could it be from the cold temperature, or is there some weird thing happening. Anything I can do?

By the way I just did water changes on both of my tanks. So I'm not worried about the ammonia levels and such. The fish I have in the 55 gallon tank are fine with the colder temperature I guess, but in case the other heater I have in there was turned up.

Okay, two of them have become more stable so I released them into my 20 gallon tank. My original one is still upside down though. Alive, but not so great looking.

Hmm... if the temp dropped super fast, it could have sent the fish into shock, and the one that you say is older might not be as hardy as the others and could be having ill effects and unable to come out of the shock and what not.

Not sure on this, but it is the best idea I can come up with, as I am not very knowledgable on the whole disease and illness things, but I think if the other 2 came back, then it most likely had to do with temp shock. Watch them all closely though.

Tank 1: (29 gal planted) empty
Tank 2: (15 gal) empty

I was curious on what you meant by floating the bag for about an hr. Did you open the bag and put any aquarium water in with the pet store water or did you just float the bag unopened? Also, what did you do after that? Did you add the store water in your aquarium? I am not a fish expert & maybe the temperature is the problem but I was wondering if it could be how you acclimated the fish into the new tank.

I hope all goes well with your Corydoras - They are fun fish to have :)

I floated the bag unopened for about 15 minutes, then opened it and started to slowly add water from the tank. None of the store water made it into my tank. I added maybe a quarter of a cup of tank water to the bag every 10 minutes. The older one eventually stablized and turned rightside up, but I left him in a breeding net I never use just incase. I think it was shock, but I freaked out. I have only had one or two fish do the whole upside down thing, and they died shortly after so I got worried. I added some stress coat to the tank since I decided it couldn't hurt. Wish all three luck. I feel like they need it now they are in my platy tank.

Glad to hear they survived. Had the same issue with a new (1 week old) heater, lost an albino cory. I went to two slightly smaller heaters on my 55 at that point to have some redundancy
