Why do my zoas look burnt?

[fishnoob~noclue]

Hey Guys,

Ive noticed a trend recently with Zoas in my 120 litre reef tank.

Zoa colonies have sort of been dying off one by one. Next up is these scrambled eggs but this time they've started to look almost burnt. I've had this frag for 3 months they've have the other head the entire time.

Ive looked for pests, but can't spot anything.

Ive Iodine dipped with reef dip, but seems yo be unsuccessful.

7.7 alk
1260 mag
0.12264 Phosphorus
40 po4
30 Nit
1.0255

Just hoping someone can see something or has had similar issue in the past.

Thanks

You have ruled out all the usual suspects?
Nudibranch
Sundial
Sea Spiders (very hard to see)
Asterina Stars

The surrounding Zoanthids look great. Unfortunately sometimes we never figure it out.

Ive tried to rule them out but I can never be sure! Im going to try and detach the coral from the rack and dip in Iodine to inspect for pests.

Thanks for your help

I like the hydrogen peroxide dilution dip better. It's worked really well for me in the past.

Good Luck.

Check for star fish...they are mainly the big culprits...also give them iodine dip and more to a different spot.
