Okay i have a RTCxTSN its 1 1/2 inches and in a 20 g tank hes acting weird like i dont see him eating, and he hangs out in a corner with his head down, and he swims around the top, and now he thinks hes a pleco trying to use his mouth as a sucker. And i was hoping to keep him in an unknown size tank (35-50 g range) but after reading all the posts i geuss thats impossible
