I bought out a system last night and this crab is in there. About the size of a golf ball. The previous owner said it eats emerald crabs for dessert. Ideas?
Its a hermit but no ideas on species. Cool orange stripes though. If its eating emeralds might want to keep it in the sump an observe for awhile. Unless theres nothing else to lose in th DT.
Yes, it's some kind of hermit, I just don't know what kind. He said when he got it, it was small like the other hermits, but just kept growing. It's not eating coral.
99% sure its Calcinus tibicen, the Orangeclaw Hermit Crab, Family Diogenidae. Tropical West Atlantic. Orange antennae and eyestalks. Eye tips white, eyes with black pupils. Unequal size claws. 1/2 to 1".
