A colleague of mine has just given me a small (1.5") reef lobster as he doesn't have a suitable set up. I have placed the lobster in a sump with DSB, live rock and caulerpa. The reference material I have on the beautifully coloured creature is minimal and omits to state the growth rate and eventual size. It is on its own in this tank and has adequate hiding places, is fed on mysis, squid and I guess whatever live critters he can catch in the sump. Can anybody shed light on the possible size and habits of the reef lobster? thanks
