Zoa troubles

clown and friends · Apr 19, 2020

I recently did a complete restart of my tank due horrendous problems with LR and an opportunity to try again presented itself with a move. The tank has been up about 3 months now and some stuff came over from the old tank including a clam, duncan and rock covered in 2 types of zoas and a RFA. Rest of the tank was dry rock. I bought a pack of zoas about 2 weeks ago, they opened for about 3 days and 2 of three are now closed and won't open and I am not sure what to do. Perams:
dKh: 9.4 (red sea)
Cal: 430 (red sea)
NO3: 2-5 (red sea)
NO2: 0 (red sea)
PO4: 0.09 (hanna ulr)

Any thoughts?

Before an after of AOIs:

Rest of tank looking good:

Tank may be too "new" and needs to mature. Many people say that zoas are easy, but I have found them to be a pain in the early stages of a new setup. After 8 - 12 months, they were much easier to grow. Anything else would grow fine, but zoas and acans had difficulties.
while they are closed, if you notice a brown film on them, use a soft brush and clean them off. I have also found they do better in a medium flow.
