What is GP S.MATT

[bengeeee]

Hey guys,
I ordered two mated coral banded shrimp on ebay and the seller was very kind indeed. In addition to the mated shrimp they sent me something called GP S.Matt . They look like closed up zoanthids but seem like they may a hard shell inside (or growing on some sort of shell).

Any idea what this could be? Sorry I cant get a pic right now.

Thanks,

Ben

Just be careful not to place them next to any corals that you wouldn't want them to grow over... they can spread fast... it is best to put them on a rock that is separate from others....otherwise they can spread right over zoanthids or other smaller corals.
