I have one half grown flavus and four small turquoise Severms and was wondering if they would be able tog get along in a 29 gal tank and I also have a clown knife fish he is about 10 " long the store said he is peaceful and could be picked on easily, could he also be able to go in in that tank with them Severms and live tog. and all be safe I have fish in tanks alone and would like to get them with others that are suitable .
