ok Last night I noticed that my long finned busy nose pleco has his tail torn up a lil but. with as soft and delicate as it is it was no shock that there were a few tears. but this morning I woke up and his tail was GONE. and all the rest of his fins are totally torn up. I've had him for a year and nothing like this has ever happened. I have not changed anything in my tank. no new fish or anything. who could have done this? I got 2 dojo loaches 1 guppy 3 cory cats and a few head and tail light tetras. any help would be great. I realy like this pleco and he is my pride and joy in this tank. I realy don't want to lose him. do u think that kind of stress will kill him or do u think his tail will grow back if he survives? he lost a good 2 inches off his tail
