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.

hes trying to feed on the pacu's slime. its actually quite common for common plecos to do that on other fish if given the chance. he could actually hurt the pacu as his sucking might cause wounds on the pacu. had to say what to do... might need to separate but maybe a more meaty diet will help.

Your pleco has become large enough now that he has developed the need for a higher protein content. If you do not intervene you will end up with a dead pacu. 2 options to fixing the problem. 1. seperate the fish. 2. begin feeding shrimp to the pleco to eat, this may or may not work depending on if he has developed a taste for slime coats.

In my experience, an 18 inch plec needs a LOT of food.
They also require protein at that age/size.
Prawns, shrimp, chopped clams, oysters, whatever.
Also seriously UP the amount of zucchinni and cucumber etc.. that you are currently feeding.
It should solve your problem nicely.

Definitely feeding on slime coat. Try Hikari Varnivore sinking pellets to get him some protein!

Thank you all very much. I will definately be acting on all your advice asap. I don't want anything bad to happen with either of them. I do understand that they need enough room.... at the moment they are in 550+ gals and if/when the time comes that isn't enough, I will be sure to have more room available for them. Thank you each again.

i think somthing might be wrong with your pacu for allowing that to happen i would keep a close eye on the pacu and up the protien in the plecos diet like the others said.
