About a week ago I got a new fish, a big 40cm black piranha pacu into my 450 litre aquarium. It doesn't want to eat anything and turned into light silver colour and always stay on the bottom. Doesn't move much, but sometimes makes very motions and bumps into aquarium walls very hard. Any idea what is wrong with it?? I'm rather new to this hobby so any advice would be great to have! Thanks!!!
