there is some sort of peculiar growth on the glass of my tank. One growth attached itself to a shrimp. To this point, no one has identified it. the idea of snail eggs came to mind, bit isn't. Something like a fungal or bacterial growth. Maybe even a animal colony. forms a small half ball attached to the glass at a single point.
Sounds like hydra to me. Does it look like sort of a little white "tree", where it attaches to the glass (or plants or driftwood) in one spot and then has little tiny "arms" almost? If so, that's hydra.
