Is this a pest or a good "bug"?

Hello all,

I am only a few months into my first reef tank so please bear with me. I have a significant amount of info to learn and I am looking forward to interacting on this site.

Any ideas what this is? It is ~ 1/16" across. Thank you!

The name has slipped my mind but they are reef safe

I believe it is a hydroid

I wouldn't be worried.

Thanks. I am not sure where they came from, but here is some good info on them:

Dots With Legs - Staurocladia oahuensis - Tiny Hydroid Jellyfish That Walk Around Tanks

The animals are between one and two millimeters in diameter. These are organisms which are turning out to be relatively common. They are crawling hydroid jellyfishes, which do not swim, but rather move around the tank sort of like a small, soft, slow spider. They move by fastening on to the substrate with their adhesive patches. The tentacles are tipped with concentrations of nematocysts. There is a red eyespot at the base of each tentacle. These organisms become quite abundant in some reef systems, and then rapidly disappear without a trace.
