Heyhey.
I have a small coldwater fish, and he's been acting very odd lately.
The other day I found him laying at the bottom of the tank, and I gathered that he was dead. When my dad got home I asked him to get the fish out of the tank, but when he walked in the fish was swimming around, almost normally, although it looked like it was struggling a bit.
This has happened a few times since then, and I don't know what on Earth is happening... what should I do/ what could it be?
