I'm thinking of getting a single Harlequin Shrimp & was wondering if owners can chime in on how much they need to be fed. I know they feed solely on starfish and I may go the "get a choc chip star, freeze, & feed bits at a time" route. The one I'm getting does eat Asterina stars so that is another option.
Dingo Giant Squid
Thanks Dingo, I would def have gone the "put the star in the sump" route but I don't have a sump unfortunately. Dang, a whole leg a week seems like so much, but I have heard they just eat all day like a starfish buffet.
MoJoe Dragon Wrasse
