Is something wrong with my zoa?

[ourfirsttank]

It looks like an area of my zoa is missing. I’ve had it about 2 weeks and it did not look this way when I got it from my LFS. All water. parameters are good. What could cause this and will it grow back? Thanks

Something could be nibbling at it. What’s your livestock in your tank?

Those should be ok but keep an eye on the zoas for the culprit and yes the damaged part will grow back
