It looks like a Hydroid Jellyfish

I pushed one of them off and it started to pulse.

Good or bad?

 

[hijinks7]

if they are brown they can be toxic. Most of the time they just disappear one day.

They aren't brown, they are white.


They are really interesting. They pulse around if I knock them off and they swim back.
