I just found this in a newly established tank and they’re stuck on the glass. When I scrape some of them off they’ll dart around as shown in the video. They don’t look like the type of hydroids that are dreaded by many reefers nor do they have the same colorarion as the hydroid jellies I’ve seen posted.
Has anyone found similar creatures in their tank? Thanks in advance!
