Harlequin Shrimp Feeding

[Pier Pressure]

Hi, everyone.

I picked up a Harlequin shrimp about a month ago at Golds and this thing has completely devoured all of the small white starfish in my tank. I bought him a big starfish and he ate it in about two days. Now he is twice the size of when I bought him, but is looking hungry again.

I do not have a sump so I cannot buy a starfish and just break off a leg to feed. Does anyone know where to get starfish at a decent price? I checked all LFS on the weekend and they all want to sell great big ones for $20+. That is pretty expensive for food!
