Your water is too clean for zoas. You should try to increase your No3. Your temp his high too, you should have it between 76-78. However I don't think this 9s your problem.

My guess would be the 0 nutrients. I'm also at 0 nitrate and phosphates (working on bringing it back up) and I'm experiencing some of my zoas melting away.

i would put my money on a pest, zoa nudis take on the color of the zoa they are eating, make it really tough to see.

You have all 0 for ammonia/nitrite/nitrate for that small of tank?

continue to dip. There may be eggs. Nudis are one of the toughest pests to completely get rid of. every 3 days for about a month.

dang every 3 days . holy crap. i was gonna dip them everytime i did a water change.

Um I think Sexy shrimps eat zoa.
yeah ive heard of sexy shrimp eating zoa's but all 5 of my sexy shrimps hosted in my leather tree/finger coral . i mostly see them eating stuff off of it or they eat the mysis and cyclops stuff that reaches them . like i literally have never seen them leave that coral .
