What's wrong with my Frogspwan

[SimbaAnto]

Frogspwan attached the picture are in my reef tank for about an year. Grown from 2 head to this. Suddenly I see polys not coming out from two heads just like other heads.

Yesterday did Coral dip using Coral Rx. On the Sandbed. Moderate flow and light.

My parameters
Alk - 8.7
Cal - 420
Mag - 1365
Nitrate - 10 ppm
PO - 0.17

Any recent water changes?
What’s your SG?
Any fish might be snacking on it?

 

[SimbaAnto]

No water changes recently. SG 35.2 PPT. Parameters has been stable for about 9 to 10 months now.

Cleaner shrimp was doing something. But not sure if it was snacking. So placed at a different spot.

All other Euphyillias doing great except these two heads and only these two heads in that branch.

I’ve never had trouble with a cleaner snacking on a coral.. Stealing food yes, but never messing a coral up.
mid a cleaner has been climbing all over it, could explain why some of it looks a bit unhappy. Keep an eye, if the cleaner is doing it again then sump him and see if it helps

Any help who have seen similar thing with your Frogspwan.

Should I try Bayer's Dip to rule out any pest? Thoughts are welcome.

You should be able to identify pests with very close inspection. Maybe those tiny euphyllia eating copepods or flatworms but i dont see any in the pic.

actually i think i see white dots on your frogspawn, are they on it or is it just air bubbles reflecting light
