Zoas not opening after 3 weeks.

[Just John]

I looked at other similar posts, but none quite addressed this. I have about 20 different zoas and they are all happy except one. Water parameters are fine. I got this frag 2 or 3 weeks ago and it has never opened more than an occasional single polyp. Moved it to lower light with no luck. Flow is low. it's right next to some happy frags. Is there anything I can do but wait?

You could try moving it, if it came from a tank with a strong light source you could try moving higher or lower if less light.

I haven't tried moving it to higher light before. I will give it a try.
