Trouble with turbinaria

[Gavynsmith]

Can anyone help figure out why my turbinaria will not extend its polyps. It’s still growing but, been a while since the polyps have come out

Check it at night. If it's catching food at night it might not want to feed all day, especially if there are fish nipping? It looks healthy and expanding growth on the edges so it would appear to be fine.

Scroll coral are very hardy. I always judge their health by the color in between the polyps.
