Just went to inspect mine as these are it's prime hours. It's actually doing really well suprisingly. I moved it to a dark corner of the tank and have pretty much ignored it outside of feeding maybe only 3 times a week tops. It's grown a lot and is very open. Definitely moving it to the pico.
On a side note...while I was looking at the sun coral, the foxface tried to attack me. I dunno if I spooked him or what but he scared the crap out of me. He was sleeping and darted out from behind his rock and slammed right into the glass trying to come at my face. His color was weeeird, solid white except for his yellow fins and rather than thrashing them at me he kept them all raised. He swam back and forth and when I backed away he went back into his little nook. Really interesting behavior. Reminds me of my old cobalt cichlid, Brutus.
