[ironhide89]

Iv attached a picture the circled area used to be full of them and iv noticed it thinning out in that area are they dieing or just moving to different areas of the rock is there anything I can do to make them healthier iv checked the water and everything seems to be fine all other corals are doing fine as well Thanks for any help

Lol. I like the sarcasm.�� all joking aside, i've had zoa colonies thin out to several dozen like they closed shop or something. They disappeared but the ones that stayed are doing great? I'm kind of confused as to why, maybe a critter/crab eating em I dunno. But, the rest of my lps softs and few sps are all doing Fantastic! So maybe zoas don't like my tank or too much lighting. I'd look at crabs or potential fish that might nip away at them. Good luck. I'm no expert by any means too bad no one chimed in.
