Emerald Crab eating polyps

[entice59]

I looked at the polyp rock in the 55 and noticed there was less, and i looked under the rock and found the emerald...
is there something else i can feed it? lettece?

I put Algae sheets in the tank and the Emeralds will eat that.

last night i saw my emerald eat my yellow polyps also but he was getting something from underneath them. so after he uprooted them i found a 2 inch brisstle worm . then i moved some of the polyps over to another rock that he removed for me. but he havent ate any yet
