Turbinaria peltata?

[atoll]

Well I think it's a Turbinaria peltata but not 100% sure. However, unlike other Turbinaria coral I have its a very slow grower for me. It's a nice deep green colour with short polyps. Only grown half the size again in 2 years while my other Tubinaria reniformis has quadrupled in size.

Yup, I've had the same esperiences even with them in very close proximity.

My Peltata and reniformis are about 10" away from one another. I have cut back a Chalice that was all but touching it.
I bought my Peltata frag the same time as a mate, his died while mine looks healthy enough, just very slow growing.

Duncanopsammia peltata, not Turbinaria.
