Montipora or Cyphastrea ... is this?

[Sea MunnKey]

I've had this for many years which I believe is some form of Montipora or Cyphastrea but I may be wrong on both. It has bright neon green polyps and last night I had to cut off more than half of it's spherical colony as it was slowly wasting away from STN. I took some shots of it right before the "cut" last night. Thanks for looking

It looks more like a cyphastrea than a monitpora. You should also consider astreopora!

Searched online and it's stated it as Nuclear Green Cyphastrea ....

IMO I believe it's an astreopora. They have polyps on mounds, or small bumps, meanwhile cyphastrea don't (As far as I've seen). Tidal Gardens has a great video on Youtube that compares the two, and explains the differences.

I agree with astreapora

Corallites' costa is bumpy and not ridged=astreopora

maybe
Astreopora randalli
or
Astreopora moretonensis
or
Astreopora incrustans
?
