Edible glass

Another forgotten photo: hydroids on eelgrass in my aquarium.

Tiny, glassy structures waving in the current. Some of the spots are bubbles, but at least a few are the new medusas just released by the hydroid parents.

Ephemeral beauty; the hermit crabs polish off the hydroids overnight, and the millimetre-wide jellies are swept into the pump and smushed into the black ooze.

The orange-brown tentacly circles are anemones on the aquarium wall.

Also, I have word verification on, because I found out that not only do I get spam without it, but it gets passed on to anyone commenting in that thread. Not cool!
