Okay yeah, I know that they are tanks that you put sick or injured fish in but the question is for how long?
I've always see people write "put him in a hospital tank" but I've always wondered about the filtration cycling part.
Do people keep an empty tank running with ammonia so that when fish gets sick they can be thrown in there with already cycle like filtration?
I have a hospital tank but it sits there empty until I need it but how can i put a sick fish in there without it being properly cycled.
What do people do?
