Well that's it!!! I will never buy another zoa! I have been fighting nudi's on and off for months. Just when I think I have them killed I find another. I have followed all the advise on FW dips with Luguls. Picked the eggs off. Distroyed the aquascaping so many times it's not funny. Have lost lots of zoa's not to mention $$$$ stupid nudi's seem to eat the most expensive one's first. I am just so sick of using a med dropper to suck out the nudi's I see, FW dipping, tweezing off eggs. I am now ready to let the nudi's eat all the zoanthid's and hopefully they will die when there are no more zoa's left.:mad2:
