Well guys...I think I might have some mutant pleco. I bought him at 4 inches 3 or so months ago, and if anything I think hes SHRUNK. He's in a 60g, fed algae wafers/cucumbers/spinach/algae off the walls. He mostly spends his time in a cave which I thought he would have outgrown by now. I mean...I don't want him to turn into a 20 inch monster overnight but I have no idea why he isn't getting any bigger.
