I had trouble with other fish sucking on the side of my discus fish and taken their slime coat but this one seems to just be taking algae out of my tank and I am happy
It's likely that he will start sometimes sucking on the slime coat of the fish. It's not uncommon in pleco's. That's why you shouldn't put pleco's with fish that are aggressive(due to being provoked). Although I hope he doesn't start sucking the slime coat from you're discus off
Good Luck
If he does I will get rid of it I have tried cherry shrimp but was an expensive meal for the fish and I found a couple alive in my filter. I will keep an eye on it
