I've had this cute lil fella for about 2 weeks now. I'm keeping him in my fuge, so his coral doesn't get stung by him bumping into other corals in my reef tanks. I'm a bit worried about the tips of the staghorn. They seem to be receding. What do I need to do to keep this coral on his back healthy? The only lighting on the fuge is a 65wt PC spiral bulb.
