I recently set up an aquarium and I have populated it with a couple of Cichlids.
A Cuban Nandopsys tetracanthus
and Seive exChichlisoma grammodes
These are both very aggressive species of cichlid and only time will tell if both will be able to inhabit the same tank.
I think I have caught the aquarium bug. When Emalie and I have our own house, one that we own, I am going to have a big aquarium with some native species.........
