could use some help with some ID`s

The first one is and Acropora, but can't be 100% sure if it is a slimer (aka Acropora yongei). Hard to say what because it is half a frag. The only thing to go by are the corallites. There are many other Acropora species it could be judging by what is there.

The second is either Cyphastrea serailia or Cyphastrea chalcidicum. The meteor shower, rainbow Cyphastreas would have lineage to those names. So since you are looking for an ID then we know it doesn't have that lineage anymore.

And the Montipora is M. spongodes.

Hey guys thanks for the info. @ frick thanks for the links. I guess once they start to take off ill get a better idea of the Acro.

 

Yeah they said monti wasn't doing so well after falling and being stung by another coral. They were gonna frag it up but I can in at the right time and got it for 15 bucks. Guess we will see how it does. Seems happy so far.
