I had two types of blastomussa ....
the smaller one (looks zoo-ish) with the tourquise centers is Blastomussa Merletti
the larger one (looks mushroom-ish) was the Blastomussa Wellsi

I didn't see a pic of the Green Slimer
the slimer is an Acropora, very different than the first two pics
it more resembles the purple millipora (which is also an Acropora)

hope the info helps ...
