Hello! So I decided that I wanted to rescue females (since you can have more in one tank).
Without knowing I decided to purchase in advance two females. Yesterday I went to go get them with the intention of only adopting one. But I then found out that the one I wanted was being eaten by the fishes and frogs in the tank and another one was starting to be picked on. So I brought them home set up my 5 gallon and split it with some fiber stuff (they said it was ok?).
So anyway I adjusted them to the water and added them in there and watched them. This morning both girls seemed fine. An hour later my seemingly healthiest girl had passed away. While my other one is now swimming around and exploring the new 5 gallon tank (since my cycling 5 gallon isn't ready but hopefully by tomorrow it will be :) ). Because I now only have her I was going to move her into the 2.5 gallon tank by tomorrow so that it will be easier for me to clean and smaller so she doesn't have to swim around so much.
Please I need advice! Here's my currently alive girl
And here is my girl who passed away this morning, she looks very strange to me
Please let me know what I should do for my little one that's alive!
