I have a centimeter large aiptasia in my zoanthid frag as soon as I saw it I remove the frag and put it in a smaller container. How would I kill the aiptasia without harming the zoanthid? Thanks
 
When addressing one or two, I've had good luck loading a needle and syringe with lemon juice (vinegar also works), then sticking and injecting the 'nem. This has worked well for me. You have to sneak up on them because if they sense your shadow they retreat back into the rock. And, I've recently learned that syringes with needles are not easily obtainable in all states. I'm in New York, and I can get one at any local pharmacy for about 50 cents each. Ask for an insulin needle, but get a larger gauge needle because the lemon juice is somewhat thicker than water, and I've had trouble loading the syringe with too small of a needle.

Another option is to blast them with a Kalkwasser solution, you just have to be careful not to raise your alk too high too quickly.

Third would be to take a blob of reef safe epoxy and when the 'nem shoots back into its rock, slap the epoxy right over it, and literally entomb it.

I hope that helps; good luck!
 
Vinegar in a syringe is my favorite method. Its also effective on bryopsis if you have a spot starting.
I did not know it worked on bryopsis; thanks for the tip!
 
I just use cyanoacrylate super glue. I like BSI brand. I've used it in zoas dozens of times - never a problem. Apply liberally entomb it.

It was a impulse decision. I had a patch starting and figured why not. It took about 3 times but it worked. I did it once a week during water changes. If someone was more persistent I'd expect faster results.
 
I spent $20 on a Paly, after a month I noticed an Aptasia I took it out but it sucked back inside the frag. I spent 2-3 days researching methods to remove it. Here’s what worked great. I tossed the frag. Why chance hurting other corals or spreading it in my tank. Sorry people it was a decision based on the tank and other corals.
