My delta tail, Chevy lives in a 5.5 gallon tank with some other fish. I bought 3 guppies on saturday and he already lived with a silver lyretail molly and a really old guppy. I also installed a heater in the tank. On Tuesday (yesterday) I started to notice some changes:
-some (not a lot) brown algae in the tank
-Chevy hides in the two homes in my tank all the time and only comes out to eat.
-Chevy is not flaring and his tail seems smaller
-Chevy seems a bit pale
SO, I have a few solutions I can put into effect:
1. I can move Jonah [the betta in my 2.5 gallon tank] into the 5.5 gallon tank and put Chevy where Jonah lives.
2. I can clean the tank and see what happens
3. I can freak out and ask someone to help me.
