How small will the plec be . I ad one with my bichirs and all he did was piss them off by knocking into them he may also take a likin to the slime coat
yes and no... i dont have any personal experience with the sailfin, but i keep 2 common plecos with no problems but i used to keep a bristlenose pleco that sucked on the polys...
I have a common placo in with my senegal they stay away from each other. I have never seen my pleco suck on a slime coat so far. You should try it. If it doesn't work, take the pleco out. It all depends on the individual fish.
