as you do, that I might make some changes. The tank is 4 foot, 260lt.....................anyway the current occupants are 1 Gold Severum, very placid but doesn't like other Severum, 2 Angels, 4 Keyholes, 2 Tbars (both male), about 12 black widows and 6 odd Serpae and 2 Common Plecs. I was thinking of moving the smaller cichlids and the Serpaes out to a 3 fter and moving in a pair of blue Acara and a pair of Firemouths. From what I can research temperment seems to be about right, do you think I have enought space? Wouldn't mind adding some glam tetras too
