Mine which im looking at right now while im writting this story, Has a very very hearty appetite, it can easily eat every day. At first it was the shyest thing in the tank, that i would hardly ever see, now he is the craziest most outgoing dude in the tank,, he will eat out of my hand,, he likes krill, clam, scallop, silverslides, basically everything even Nori! He has not killed nor chased anything in my tank, but i do see him picking at hermit and turbo snail shells, picking at the algae, but i havent seen him murder anything YET,, he molts regularly and and has the hugest molts, BUT he is getting to big now and i dont know what im gonna do.. Not his body but his antenaes,, they are like 20" from point to point and bump into everthing,, has not touched any of my clams or corals as well.. wanna see some pics?
