Zoas Retracted... Advice?

[T4rdV4rk]

Hi I'm new to corals and reef central. I received a zoa frag pack 1 week ago. Some of these opened immediately and are clearly growing. Others are reluctant to full open and look sad. Have added reef roids and feed shrimp. Some of the zoa/palys open for the food and others don't.

Any advice out there? Give it time? Want to make sure I'm not killing them.

Nitrates aren't high enough to register on my test strips. I think the test strips are good because they activated when I tested my rock while it was curing.

Flow is moderate...? I've tried 1 vs 2 of my powerheads and that doesn't seem to make much difference.

I just bumped the lights up by 10% because some of them appear to be stretching. We'll see what happens.

it takes time for them to settle in and get used to the tank as well. Give them a few days, then if they still seem unhappy try moving them to a new location. I wouldn't bother feeding either, they don't need it. Let them settle in and start growing, which takes time, before trying to feed.

If all close up it’s something with your tank. If just a few that’s normal to have a few die off.

Food not needed. Just light but don’t go above the 35% in shallow frag tank.

Make sure there isn't any asterina starfish on them. I have seen them eat my zoa's
