Caulastrea Species

[kireek]

Is there a method of distinguishing the caulastrea species apart.I made the mistake of placing my red and teal variety next to my green colonies.Let's just say the red and teal won.I prefer to group them together for ease of feeding and to save space in my Nano.

An easy method? Not really. The species differences are really down at the skeletal level in this genus.

Caulastrea connata
Caulastrea curvata
Caulastrea echinulata
Caulastrea furcata
Caulastrea tumida
