does this hitchhiker need to go?

[corpusse]

I can't remember what this is, but it was identified at one point. It was deemed to be safe, however I noticed it creating a hell of a lot of waste today. I have snails and crabs for a cleanup crew so if this things not nessessary I will have to consider getting rid of it. There are actually several in my tank this being the biggest one.

The zoos its on have been dying lately I don't think thats realated but theres still a few on the frag that look good. Heres a video clip to get an idea of the waste, as well as a still pic.

Nice Picture!! Stomatella varia, He's just making out with himself. No worries.

From http://www.reefcorner.com/SpecimenSheets/stomatella_varia.htm

"Stomatella are active day or night, but come out mostly at night and are fairly secretive during the day. A look at the tank walls after dark with a flashlight will usually spot this critters if they are present in the tank. They will reproduce in the reef tank, but don't seem to reach nuisance population levels. Breeding has been observed during the daytime with all individuals climbing up to high points on the live rock and simultaneously releasing their eggs and sperm into the water. This can cause the tank water to look milky for a short time, but is nothing to worry about. The filter feeders get to eat well when this occurs.
