Harlequin Shrimp Feeding

[Pier Pressure]

I only have the one shrimp and am going to try the frozen starfish thing. I threw a fresh leg in last night and shall see if there is anything left of it today. The blue hermits seemed interested in it but the harlequin did not come out as he prefers evenings and nighttime.

Patrick1, how did you ensure that your harlequins were the ones eating the leg and not some other creature? Are harlequins the only ones who are interested in eating starfish?
