I.D. Please

Not sure what this little green dude is. There's actually two little humps sitting next to each other. Sorry for the rotten pic, I tried to get a decent one but can't find my tripod at the moment. It's the little green guys to the left in the pic.

Bubble algae?

[brewercm]

Not bubble algea. I have some of that unfortunately that I'm trying to fight off. They are a very lime green color and look to be either some sort of sponge or coral. Just not sure what.

Do you mean this?

I believe that is a sponge.

[brewercm]

That's it. There are two little mounds mixed in with all the polyps.

Not sure what this little green dude is. ....
I am not sure either. A better picture is needed for certain ID.
How ever, I know for sure that your Montipora digitata and The Acropora sp. that you have there will not likely do well long term in the polyp field. IMO, in a SPS tank, you need to eliminate these button polyps because they can really be detrimental to your SPS.
Both frags look great and have beautiful color.

I was looking at the green blob behing it. Yea, I think that its yellow sponge too.
I have a bunch in my tank. I have some yellowish tunicates (seasquirts) too.
