Some of my zoas have some white stuff on their tentacles. Has anyone seen this before?

From the picture cant tell anything much but maybe a slight lighting morph?

Looks like they could be morphing due to lighting? hard to tell ..you can give them a dip and see if that helps any

When they physically change from their original appearance due to mixing with other species,lighting,water chemistry etc. best way to describe it i guess lol

Higher lighting on zoas can cause a whiteing of the skirt, or on the outer rim of the disk, iv had it happen to mine, Nothing to be worried about!

It's a slightly pinched skirt. Possible a dip would help. Or something may be nipping them. Also lighting sometimes affects this.

You guys have a good eyes. I couldn't see anything from the pictures

I'll keep an eye on them. Hopefully it's just the brighter lights and they'll adjust. Thanks everyone!

Or they may be getting stung by another coral.
