Pink Star Polyp help

[dustintx]

So yesterday I bought a colony of pink star polyps,super pretty. Doesn't matter where they are in the tank,they refuse to open. I also bought other zoas and GSP and they are all opened.
It literally just looks like a rock with coraline algea on it. Lights are good,water is good,flow is good. So not sure if this is normal or should I be concerned.

Stop moving it around!

Check your parameters. Post them here.

Give it time.

Nitrate .2

Don't have testers for anything else as of yet.

Sometimes my GSP closes up for days at a time.

I have found that they are pretty sensitive to alkalinity, pH and salinity.

Yeaterday I moved it to a darker side of tank,adjusted water flow and this morning I can see 2 polyps opening. We'll see what happens.

Within 10 minutes of turning tank lights in,there are about 5 polyps opened. I'm sure it will be fully opened by the time I get home from work tonight. Thanx guys.
Pinkys are sensitive compared to my GSP.

They have finally opened up about 60% or so.

I've noticed the same with gsp. The more you move them the longer they stay closed up. They generally do ok just about anywhere in the tank. But they can only take so much moving around. Pick a spot and leave it be for a few weeks.
