ya i have a frag rack attached to a float magnet i'll try and isolate the remaining pieces to see if i can catch the culprit in action =/ might as well list my fish and i also have a decorator crab which may be a problem in the future but he is to recent of an addition to be the main problem.

- flame angel
- clown of some kind i forget the name
- blue spot jawfish
- orange spot goby
- 6 line wrasse
- lawnmower blenny

all dwarf angels have a risk of eating corals, including zoos. observe the flame carefully too.

I had a peppermint shrimp eat all my feather duster worms and when he was done with them he went after my zoas and did a pretty good job on them before something got him.

Keep an eye on him for sure.

Eunicid worm? They can lurk in your tank for years before they become large enough to have a noticable impact.

+1 on the worms as a suspect. If they are disappearing overnight then it is unlikely(but not impossible)that shrimp, fish or nudis are doing the damage.

i had a tiger cowry wipe out all mine once i didnt find out it was him until halfway through my last colony

+1 on the eunicid worm. I had one that mowed down colonies of zoos and ricordeas overnight. You'd have to have a lot of nudis to take down that many zoos overnight. And with that many you'd definitely see them IMO.
