Hitchhicker coral ID

[Demm]

well i think this might be an SPS since it's encrusting on one of my live rocks, it just kinda just popped outta nowhere and started to grow on one of my rocks. it has little polyps that extend out about 3mm or 4mm from the base, and when it's spooked it pulls back into it'self. it's also growing in little circle patches


hoping to get an ID on this so i can start caring for it. cant get much better pics because the coral is still pretty small. i have about 4 or 5 patches of them now.

Looks like a developing Goniopora or Flowerpot Coral (LPS)

Still much to young to be sure, but could be a Porites or Goniopora. Porites is very common on live rock. From my own experience, they tend to die off as the tank/rock matures. I get the feeling they want something that my tanks don't contain. Take notes on water quality and see how they do.

looks kinda like a galaxy

If it's porites, I've read they like strong current and bright light. When mine doesn't get strong current the polyps retract and the coral gets this glossy look all over it. With a lot of current and occasional feeding it's spreading and growing fast.

I have the exact same thing on one of my rocks. I don't think that its either of the suggested corals. I have not been able to find any info on it. Mine started with a couple of polyps and has spread on the rock. the polyps have stayed that size. I have mine under 250W metal halides and medium current and it seems happy and still spreading. It's not agressive and gave way to an acro that is growing right next to it.

Now I think it could be Madracis, not Porites.

Other possible candidates may be Goniastrea minuata or the previously mentioned Madracis, but without seeing the skeleton better, it is only guess work.
