thanks, we already got a male and female erectus at aquarium designs. we watched them eat voraciously before buying them. they have already eaten for us and are constantly patrolling looking for food as well. for flow, we have a koralia nano that is pointed at the water surface, so there is nice gently flow throughout the tank. they have been cruising around some and hang on to the gorgonians as well. the male is staying a nice bright yellow with great striping on its head and face, but the female remains solid black.
