can anyone recmmend a fish or other organism that will eat zoos?

You're not able to baste them with hot water?

We have a three spot angelfish (flagfin) that is a Zoa exterminator!

Filefish
 

We had a bristle tail filefish that was purchased to eat aptaisa, and all it ate were zoas, might be worth a try. If I remember correctly, it was under $20 from a lfs in Vancouver.

Here is a bio on them from Live Aquaria: http://www.liveaquaria.com/product/p...62&pcatid=2562

thanks for the info, I think I'll just stick it out for now! (until all my precious acros are covered with plain zoos!)

The aptaisa control takes them out I tried to kill a few that were in my zoes and it took out the surrounding ones as well. Might be worth a shot.
You could try some zoe eating nudies they should not be to hard to come by.
