Could be a goniopora? How long of a stalk are the polyps on? Does the stalk get shorter and longer during the day?
I would guess goniopora too. Isn't the main difference in goniopora and alveopora the tentacle count? I thought goniopora had 24 per polyp, and alveopora only had 12.
Isn't this goniopora? It doesn't look like the other. Sorry for all the questions. I just like knowing what I have.
Yes, that's a goni. They have many different colors and growth forms. Some have polyps so short they look almost like a cyphastrea. Yours may not be a goni but I bet if it's not it's a closely related species. Do the polyps retract at night? Is there a stoney skeleton the polyps retract in to? If you blow water at it with a turkey baster does it react? Is there a matt of tissue under the polyps instead of a stoney skeleton?
It is stoney and they do retract. It does react to a turkey baster. It eats mysis shrimp good unlike the other goniopora.
