This is all good stuff guys keep it coming, I like the idea of a flagtail and will ditch the Columbian shark and get a couple of pictures instead. Regarding the Texas or gt I always thought that they can become VERY aggressive but u might be wrong? Was thinking along the lines of a few mire cichlids cause of the rock caves going in one end of the rank. I need to source a large arched piece of wood for the tank can I use anything other than bogwood?
