I'm sure this may have been asked before but I presently have 3 2"-3" Polypterus senegalus (Senegal Bichir) and was wondering if it would be safe to add a Polypterus delhezi (Armored Bichir) of equal size? They presently live with some smaller african cichlids as well as 1- 4" african knife. Tank is presently a 55 with lots of caves and driftwood on the top to allow for hiding. Thanks in advance from those more experienced.
unless you happen to end up with a super aggressive one, shouldn't be a problem.
