this morning, i found my pleco dead, all torn and beat up with a long horizantal cut across his belly with his guts falling out. who could have killed him? i have no idea who would have done it, but im almost positive it wasnt the blue acara(who i highly doubt could have killed it if it wanted to) or the oscar since hes extremely peacful. the pike can get aggressive, and occasionally chases around the acara and pictuses, but ive never seen him go after the pleco. could it have been the sailfin? please help if you can, ive been wanting to put in more plecos but i dont want to buy them if they just get killed.
