well to make a long story short my g/f bought a 44gal corner tank from my mother...the tank was stocked and all the fish where kept..i helped her move the tank to her house and it all when well, we didnt lose 1 fish (15 total)... my question is: today i noticed that most of the fish seem to have torn fins..i dont think this is a result of nipping...is this an illness and how can i treat it if so
