I do have a buying history with them, and they are the most reputable dealer around. They have a live arrival guarantee and their policy is to refund your money if the animal dies within 14 days of arrival. I (and I know many others) have had good experiences with them in the past. They did note it on account, so if (or more likely when) I call and tell them the starfish died they will basically either refund the money or I can use that amount towards a future purchase (though would need to pay shipping).
I think the coral might be okay, but am really sad about the brittlestar. It's jsut really disappointing. And I am very worried about it causing my tank to cycle (this is my tiny 10g tank that its currently in - I didn't move it to my 90 this morning given its failing condition - I figured if it has any chance at survival, moving it again will likely do it in). Will my tank be okay with those broken off starfish legs in it that I couldn't find? They probably got buried in the sand :( All I have for a clean up crew are a handful of nassarius snails - will they handle starfish legs?
