I'm looking for a catfish to start of with as a beginner and i found out about one species named the red tailed catfish. but i found out that it grew to 5 feet and needed lots of room. but i loved the color and the way they look around for food and i heard that they even play with balls. so if anybody knew if there was a catfish that looked like the redtail but doesn't get very that would be very helpful!
