Hey folks, when I set up my first tank a few months ago I put in the fish you see below (in the bigger of the two) one of which was sold to me as a "Gold Ancistrus" and was about 2cm long. I got him because he was kinda sweet and because I'd been told that he's an awesome alge cleaner. He's still sweet and about 3cm long now, but I've been told conflicting things as to how big he'll grow, some folks have said that he'll get as big as a common Plec, others have said 3 inches max. I'm not too concerned because I'm intending to invest in a much bigger tank before too long, but I'm kinda curious. Is he a monster or a tiddler? Any help appreciated!
