Zoa eating nudibranch

:facepalm:

I broke rule number 1 and 2. Didn't dip and didn't QT a new zoa colony. I have now found 2 zoa eating nudibranch in my tank. I am going to assume that means I have many more. I have also seen a couple spirals of eggs on the zoas and rocks in the area.

For those that have had to eradicate them before does flatworm exit work ok? From what I have read it says it is reef and fish safe to use in the DT. Will it also kill the dusters, good snails or hermit crabs in my DT?

I have a good amount of rock so I would prefer to treat the DT instead of using a QT since I don't have one big enough for all the rock that could be exposed.

Meant to open this in the nooby section. Will repost there.

in my case i just filled a small Tupperware with ro and put the colony in it. the nudi's are easy to see even small ones when the zoas are closed. after that i just used one of my wife's sewing pins to remove the dead or dieing nudi's.

the real trick was not letting my wife know i was using her pins to kill slugs.
