Unknown Coral

[chris489]

Hi guys, can anybody help me identify these corals?? They came in on some live rock.
They are light brown in colour and fluoresce slightly under blue light.

Polyps green can't tell the color but they are polyps.

some run of the mill palys.... I would either try to pull them off, and keep them on their own small rock isolated from other rocks, or simply nuke them now. Those things can go wild & take over your tank. They will sting any coral next to them too. If you decide to keep them, once they run out of room to expand on the rock, they will let go of a couple polyps at a time, which will float around, landing on nearby corals or rocks until they lodge into a crevice & start growing again.

Thanks for the reply, I got the rock back in May and there was just one very small one on there. They seem to have sprung up since I changed to led lighting. I had metal halide up until 5 weeks ago
