Hey , hacker , as Lornek says, lolks like a common. I realize u are new to the hobby and dig this guy, but we cant see your full tank and i was wondering if he has a cave? Plecs love to feel safe in a hidey place, caves are in their natural environment,so usually a good way to go .They also need wood to rasp on ,which helps their digestion. Just hard to say what you already have in his tank. Hope this helps.
