Hello everyone. The weirdest thing just happened. When I woke up, my fairly new Bangaii Cardnalfish was doing fine, a few hours later (around 9:30), I came to check on him and he was laying on the bottom not really moving. However, I just came back in to check again, and he was swimming around. Is he pulling an April Fool’s joke on me? What should I do? Leave him be? Move him to quarantine? Thanks in advance.
