. Steve Allen here tonight) I have a 14 month old 180 gallon (72x24x24) reef tank with 4700 gph overall current flow. Currently there is only one orange percula and one black percula in the tank with future plans on adding two to three purple Firefish and possibly a flame angel. I have read your article on the Sohal and the FAQ’s sections at length, but still must ask you point blank. Is my tank too small to properly house a Sohal if it is the only other fish added to this tank? Would it be aggressive toward the clowns and Firefish? I am looking for a nice show fish that is “out of the ordinary” to help finish off the reef and the Sohal came to mind. I have a friend with a 500 gallon that I can move him too when he gets over a foot long. Thanks
