im prety sure the polys not sick. hes prety active and eating. it only occurs when the poly goes near the pleco. i have 3 plecos in that tank. only one is the problem. it happens to be the biggest.
hmm as they get older they require more protein. Maybe wasn't getting enough and so took to the slimecoat.
Or could be chance it was the biggest.
Either way, it would kill the poly if they aren't seperated.
