Identify this!?!?!?!

I have a couple of rocks with these on them. They glow a little under my led's. I kinda like em but now I am starting to worry a little.

You should start worrying if you have the ones I have. They spread around pretty fast and no way to get rid of them it seems...

I had something similiar to that, but much more greener.
It had light blue tips as well. I had to do a manual removal which was a PITA.
Nothing I knew would eat those, probably just doesn't appeal anyone's taste buds.

Is the best option to feed less and control water parameters?

Should I hydroids touching corals out or can I let them be? They don't seem to be bothering them?

i take a wire brush a scrub scrub scrub and a\occasionally a razor blade to cut.....but since there is a nice size colony on a base rock i guess ill never get rid of them

They dont bother my corals,but they look bad and grow fast

 

[Steve Hwang]

wow this is the worst pest in the world!

I guess I have to learn to live with them.

I have them too, ten emeralds in a 125 have a problem keeping up ..
they eat them but slowly..
I have sworn off all hermits but I am entertaining the thought of a couple dozen till these are under control
