My juvill datnoid's head looks like starting to rot (Can a pleco suck on a datnoid's head and cause damage?), my small datnoid turning to black overnight, my catfish's dorsal fin get torn off and the only fish in the tank without any damage is the Sailfin pleco.
Do you think a 5" Sailfin pleco causes all these? I heard they are quite territorial and aggressive.
