Folks, if you've recently upgraded or renewed your annual club membership but it's still not active, please reach out to the BOD or a moderator. The PayPal system has a slight bug which it doesn't allow it to activate the account on it's own.
I generally place my new zoas in shaded areas on the sand bed until they acclimate to my lighting. I find this betters my success rate with new zoas. hth.
also you might try checking for pests at night. thats the best time to catch nudis, for example. If you successfully remove them you will be surprised how quick they open back up. good luck.
