[AlonelyCody]

OK i have a question. I have what lookes like snowflakes on the glass of my tanks. What are they? Are they a type of pod? Or baby starfish? LOL I am clueless about this one. (O: They are white and about a 16th of an inch to small for my bad cam to take a pic of. Any help IDing these would be wonderful. Thank you!!

Sounds like a small jelly. I used to see them but not anymore. I don't think they are bad.
