"Tiny Dancers"

[jlfritsche]

Well they kinda dance. I have what look like baby jellyfish, (cant get a pic too small) that attach to the glass. I am clueless as to what these are, when I scrape them off the glass with my mag float they "dance" to their next chill spot....any ideas.
thanx

Hydroid jellyfish. They are usually harmless and seem to go away over time.
