I have a tri-color anthias in my 55g tank. it does fine under the lights i have. 2x 250 mh.
It also gets fed like all the other fish in the tank., once a day except Friday. No feedings on Friday. Its color is bright orange, healthy & very active... the anthias has doubled in size & i've had it for over 6 months.
Now mind you, this is a Tri-color, I can't speak on behalf of any other anthias..
