Hi, My family has four black tetra(aka: black skirted tetra, black widow tetra) and an algae eater in a 15-20 gallon (56-75 liters) fresh water fish tank. I know this might sound awkward but all they do all day is swim! I know (duh) that is what they are supposed to do, but how do I identify if they are bored and is there any remedy? If I were a fish in a tank I know I'd go crazy! All answers welcomed!
