Need Help Identifying This Guy

[See Gee Sea]

Hello! So I'm in the early stages of adding live stock to my tank and noticed this guy when I added some hermits and emerald crabs. The picture is blurry but it pulsates almost like a jellyfish. Any ideas? Thanks in advance!

Hard to tell from the picture but probably a Hydroid.

^agree. Hydroid jellyfish. They are mostly no big deal unless you have seahorses or pipefish. They usually are there one day and gone the next.

Thank you both!
