I am not sure just what kind of pleco this is, it's the kind that are always in every fish shop's tanks.... I never knew there were so many types of plecos... Anyway, my pleco is roughly 18" and it has recently been 'sucking' on my 24" pacu. The pleco will try to keep up with the pacu when it moves away. Sometimes the pacu will stay pretty still with the pleco kind of 'feeling' it all over, and sometimes the pacu will actually lay on it's side while the pleco 'sucks' on it. After a short time, the pacu starts to wriggle around and go to swim away and that is when the pleco seems to chase after it trying to latch unto it again. After the pacu swims away too fast for the pleco to keep up, the pleco seems to forget about the pacu for awhile. What is this pleco doing??? Is it trying to hurt the pacu? Does the pacu have something on it's body that the pleco is actually trying to eat?
Any advice/ opinions will be appreciated.
