Hi all, I have 4 clown loach, several electric yellow young, 2 longfinned golden bristlenose catfish and 2 angelfish in a 2mtr x 600 x 600 tank. The tank has plenty of rocks and hiding places and some twisted val in it. I was wondering if a couple of Severum would live with peacefully with the other fish and if this size tank would be suitable. Because all the other fish are yellow or orange and black, I was wanting to get something of a different colour ie: green, dark red or dark blue. Any help would be appreciated.
