Is there a catfish that stays 2 ft or under that has the same type personality as a Redtail Catfish? I'm building a 700g (48"x96"x36") currently that will house some large cichlids and oddballs, but even this size tank doesn't seem bigger enough for a fish that can reach 3.5 ft. Plus I think it would eat some of my fish that stay in the 12in range... But I really like their friendly puppy dog personality... Are there any cats that stay a bit smaller but have the same outgoing interactive tendencies? Thanks!
