After a little research online it looked like I had several ways to get rid of the critter. I removed the piece of rock from the tank and poured lime juice on the debil. I let the rock stay out about 10 minutes, did the routine again, washed the lime juice off with some RO water and returned the rock to the tank. It's been 24 hours I don't see him anywhere. I think that did the trick.
Cool! I just got to thinking last night what if Jerry didn't know to not just scrape him off (it can create lots of little aiptasia any where a cell survives). Glad you researched and did it correctly.
