LOL@rainbow bta...
Entacmaea quadricolor comes in two color variations and maybe two subspieces... it's debatable... since the common green BTA will never grow as large as a rose BTA... but yet they are the same species somehow...
a GBTA can be closely colored to a rose... but a rose is just a rose... some have white speckles, but rarely keep them in artificial lighting... the also, the green coloration in yours somewhat goes away when fully extended... and it does look like it's splitting... mine split several times... good luck with the clones... they walk around and hide, then out of no where they're on top of your favorite coral...
