Maybe zoanthid nudibranchs.

You may wish to try out Fauna Marin's Pest Control that's available at Marinelife, Madpetz or Iwarna.

Effective against zoa nudis, acro eating flatworms, amphipods, bacterial infections and can be used with sensitive species like xenia. A 250ml bottle will last a long long time (30 drops or approximately 1.5ml per 4 liters of water). This should equate to about 160 standard 4L dips.

Your KH is low.Try to maintain it above 8

IMO, 7.3 kh, if consistent is ok. But like what Sherman advised 8+ is better.This might be your problem, but remote.

Other ways that have worked for me 1 ) Bring the frag out, gives it a cold shower under sprayed tap water. 3 X 1 min. The zoas will closed up, so its safe. The culprits, whatever they are, will be hopefully flushed off. ( 2 ) If unable to take the frar/rock out, then blow the zoas colony with a wave maker or whatever you have, to send the irritants away. ( 3 ) check for the small irregular shaped small white, greyish star. ( i dont know the name, nvr can remember ). They are zoas eater. Take them off and toss it into the tiolet bowl.No need to flush !( 4 ) If its nudibranchs, consult the pest controllers like DR FuEl.

Good Luck,

also check if your parameters swing often, it also contributes to the problem.
