When it was eating, I fed it krill and silversides. The last time it ate was two weeks ago and it basically ate the silverside and then regurgitated it. I do have a metal hallide fixture on order. I bought a Hamilton fixture with 2 250 watt halides and 2 110 watt actinic VHO's. I hope this does the trick. Check out the before and after pictures I took. Sorry the after is a little blurry.
