It looks like a Caribbean Corallimorph to me.

Yippee! I just discovered one in my tank a few nights ago and was concerned it might be something bad!

Depends on what you consider *bad*, what else you have in your tank, and whether or not you have the larger species:

"...tentacle tips are extremely sticky, like flypaper, due to the presence of powerful nematocysts. This fact makes the larger species from the Indo Pacific region unsuitable for aquariums housing fishes, which they readily capture. They also can catch mobile invertebrates such as shrimps and snails, and sometimes "attack" sessile invertebrates growing on adjacent rocks, enveloping them in the gastric cavity through a widely opened mouth. Pseudocorynactis spp. can be fed daily, but only require twice weekly feeding to keep them healthy. If they are not fed frequently enough, they shrink. There is a marked behavioral difference between the common Caribbean and Indo-Pacific species."</em>
