i recently purchased two corals from my lfs, despite not knowing exactly the species from which they belong to.. i had to buy them since they were a steal and i couldnt pass up the offer. anyone have an idea what type of corals they are? im aware one of them belongs to the acropora family but what's the species? the acro coral is about the size of a fist and it was on sale for $30 and its a deep brownish color (it looks a lot better in real life than in the pics). the other green coral which looks like some sort of plating coral is about 5-6 inches and i bought it for $15. i would greatly appreciate some help, thank you.
