I have a 265 gallon tank, have 6 muskies and peacock bass, pikes and a gar, they all get along fine, however i just added a 13" (same size as muskies) redtail catfish, some people i talked to said everyone will be fine as long as i keep feeding them all a lot like i do now, others said the redtail will slowly eat everyone in there haha...any recommendations/comments? thanks
