So I've got 4 little Endlers in a 56 gallon. It's a new tank so there are plants, but just the 4 fish. One's looking a little pale and I think a little distended. I'm very new to the hobby so I don't have much to compare it to. I've got a small quarantine tank all set up, but I can't catch the fish. So, oh gurus of the aquarium, what are your tips and tricks for catching a 3/4 of inch fish in 56 gallons of water without uprooting every plant or scaring all the fish to death. I tried to catch this guy for 30 minutes and stopped because I thought that I would stress him to death even if he isn't already sick. Suggestions? At this point, I think I'd have more luck just whistling and seeing if he turns himself in. thanks!!
