This just sprang up in my tank. It glows at night under the blue LEDs and is fluorescent green during the day. Any ideas? Thanks for the help.

I should have said, they are about 3/4: long, as wide as a straight pin, and the top is about as big as the top on a straight pin.
Wow, thank you guys. Never even considered being stung. I'll get a pic. under white light but they don't change, nor do they with draw in light like a featherduster or tube worm. They always have this glowing about themI agree with green colonial hydroids. They have some nasty stings. May even sting you so be cautious.
I don't really know the species, it is a hydrozoan of some kind. You can monitor these and watch for rapid growth or if they slowly spread or don't grow at all. If you want to keep them that is.Wow, thank you guys. Never even considered being stung.

Live rock from the Atlantic ,Florida,Picture under white lights to be sure. Was this live rock or dry?
The non fluorescent hydriods seem to act like a plague,Okay all, I'm trying to do some better research on these hydroids and I'm seeing a lot of "pull them out", Are these bad for my corals, or a cool addition? Wish you didn't have to research 10 articles then decide.
It is a pod rich environment so I should b concerned? I will get better pics. For everyone to see before the hemo squad is called . I really appreciate everyone's input. Thank you n will put up the other pics asapWhite light pictures come out clearer so we can get a better identification of the critter. I rather like hydroids, myself, but they are tiny predators and will eat whatever pods they can catch.
Yup, they love pods.It is a pod rich environment so I should b concerned? I will get better pics. For everyone to see before the hemo squad is called . I really appreciate everyone's input. Thank you n will put up the other pics asap
My tank is a Mandarin pair, and coral tank. We don't need extra mouths when I'm hoping to get a picture of a little reef w lots of baby dragonet's on it. A guy can dream lol. They are gone w putty.If you've got a lot of pod-dependent fish, it may be better to eradicate them (the hydroids, not the fish XD). My pods are mostly algae munchers and breed faster than the hydroids can eat them, so it's all about you tank's balance
