    Looks to me like a Phsogyra sp. which is from the bubble coral genus, but this one doesn't form bubbles.

    But then again it could be a Galaxia, I would need to see it in person to definitely id it.

    Thanks Carlos, more than welcome to come have a look. But if this helps, it is almost like a encrusting coral, but with more soft polyps on it. Short, about 1mm. :)

    OK, having a better look with my phone, which has a HD display, it's definitely a Glaxia coral. Watch for the sweeper tentacles, very powerful nematocysts.

    Hi Carlos, I had a look on the net at the galaxia coral and I can see that it has like individual heads, easily seen when the tentacles are retracted. This coral is has a flat surface, encrusting the rock its on and the little green polyps or short tentacles forms little circles. I'll get a better photo for you, maybe one after lights out as well. But thanks for the input. Got it from Idol and even they weren't sure but did say that it could be a encrusting monti of some sort.

    Then it's a Galaxia. I remember we had some in stock. Let me guess, it was in the middle coral set of banks at the shop?

    It's Hydnophora. Very distinct corallites. It's also got a very powerful sting.

    It's Hydnophora exesa. Importers constantly confuse it with other corals. I saw three here at the Durban LFS last week that were all mislabelled (probably from the same importer).

    Just a question, the galaxia, does it have a stoney base with the soft tissue tentacles at the top of each individual stem? Cause this coral is about 5mm thick at most, cannot see the base which is attached to the rock and also is one piece, grey-ish brownish with just the fine green polyps protruding from it, not individual star-like. I had some galaxia in my previos tank, and know about their long sweeping tentacles, I'll post a pic of it's dead skeleton from which it's tentacles protruded.

    Thanks for the input though, I appreciate it. The only thing that throws me is that it doesn't have a stoney base and doesnt look the same as the pics on the net, not even closely.

    We didn't get Hydnophoras. H.exesa have branches extending upwards. What you have is a Galaxia[​IMG] Did it look like this? This is my Galaxia. I know the coral you have, saw it there for weeks.

    Galaxea has very distinct individual corallites that protrude quite a way from the base. They're regular in size and close to round. The polyps extend from the top of each corallite like a flower:

    Hydnophora has a very distinct valley like pattern to the corallites, and the polyps extend out from the base of the valleys. You can clearly see the elongate corallites in the pic in the first post. It can be branching or encrusting, this isn't an identifying feature:

    Sorry to say Carlos, but still not, also had a look at the hydnophora exesa, also not. Looking at the pic you posted, the ones on the net, to me, doesnt look the same. I dont know. All I can say for now, it's doing well and looking good.

    Looking at both the images, I would lean towards @Lord_Blackadder, I've had a Hydnopora and the similarities are there. @Shaun88, does the rock formation look dome shaped/almost mushroom like?
    @sweetnsour @Adee?

    Hey @gMAN , yes, it does havd a dome shape to it and as @Lord_Blackadder said, the polyps does protrude from the "valley" area.
