Luckily, a blade drifted close enough to the glass before the goodies were all gone.

I looked for reproductive polyps, like little goblets, and without tentacles, but didn't find any, possibly because these are all young colonies; single stalks with sometimes one or two branches. (Photo of older colonies here.) If there are still any left tomorrow, I'll look again.*
|Two small hermits on a blade of eelgrass, to show the relative size of the hydroids. The eelgrass blade is 1/4 inch wide.|
*Update: In the morning, all the eelgrass was clean. The hermits had been working all night.
