Without a better picture I believe the small ones are "mini turbos." Reef safe and good fish food :-p

Tulips are predatory which can be bad. The one guy was convinced it was not a tulip, but regardless it was eating his zoas. Yours appears to have a prominent spindle shape like a tulip. It is definitely worth trying to find a positive ID on. Wetwebmedia.com is a great tool for IDs

Still keep an eye out for crabs and nudis in the meantime. The nudis can be tricky to spot. The eggs should be easier to find.
