hrmm well i have a 6 inch motoro that always had a short tail and i just never noticed that it was bitten off. but then recently i just got a new motoro at about 3 inches and it had a long tail. but after 2 days in my tank the tail got shorter so im assuming a fish bit it off. and im guessting its my clown loaches or my mbu.... is this a problem? cuz my big motoros been living well like that. but im just worried now that i actually noticed.
