ID These Critters?

[catfishblues]

I've had a recent bo of copepods finally (yay) and while looking at them I found these little guys on the glass. I had to use some glasses to magnify them to get a pic, but the almost look like tiny sea stars with a base and 5 or six arms.

Those look like hydroids. Typical with a new tank and will disappear on there own.

Makes sense. My tanks pretty new.

Are they good? Bad? Don't really matter?

There basically hydroid jellyfish, they are harmless and will die off as the tank matures. You can pluck them out as well.

It’s difficult to see but if it has five limbs and came through amphipod shipment then it serpent starfish it’s reef safe.

Hydroids can come in on a lot of things and starfish don't always have 5 legs. But I agree, the pic is blurry. Welcome to R2R by the way.

Medusae hydroids. They'll go away on their own. The amphipod shipment was likely a coincidence

I checked Google images and for sure hydroids. Thank you everyone for your help!
