What do I have here?

[Mystery Fish]

Sorry for the potato quality pic but these guys are pretty small. Most are the size of a large grain of sand and completely white. I have a standard 55 that’s been up since 12/20/20. I’ll find around 30-40 on the front glass. Scrape em off and a day or two later they’re back. Thanks in advance!

Hydroid jellyfish.

That was my first guess. Any thoughts on how to proceed? I’ve heard they may resolve themselves.

Thanks for the help!

They are unwanted as they have tiny stingers. As the tank matures they should disappear. I am not aware of a specific therapy.

They'll starve out on their own
