I got My Banggai's Now for the Hard Part

[DOO-E]

Can you get frozen Mysis shrimp and if not r they easy to rear so i can feed them to my fish. I have a refuqium with a fairly fine scrren door so i can open that and let the shrimp fall into the tank. But O man i am so excited and i called the LFS yesterday and they said that they have in some green star polyps. But they arnt opening its been 3 days and he has only seen 1 or 2 polyps open so there might be no or little hope.
