Pink diamonds are opening oddly

[chyeaboy2007]

All my parameters are reading good and have had good growth on them but they dont open all the way they have only opened like this for a mouth now even the new little guy only opens half way as seen in imagin attached and not 1 of my other zoas do it so just wondering other pictures are of my other zoas just fine

I don't see the issue. They look fine to me.

They never open all the way they only open half the way the left side of them never unfolded all the way to show off the nice green fingers like the right side

The polyp on the right of your first image has part of its frill curled slightly. If it does that consistently, I would think a worm or something lives in the rock and touches it sometimes. Harmless.

They all look fine, aside from that. Pink diamonds don't have long tentacles, so they aren't going to be the shape of the other zoas you have.
