Awsome looking fish , I had 2 of them eating frozen misys blood worms like pigs , over time apetite grows and it will always end up feeding on your acans
I had one, for several years, that never even looked at any corals, luckily. It ate all frozen foods that I offered it and did wonders on my Aiptasia! The food I mainly fed was Rods Food Original Diet.
I have a marginalis. He definitely prefers strips of pure meat like scallop or shrimp, over prickly shrimp like mysis, especially ones that still have legs and antenna and such.
