Lots of my zoanthid colonies had become infested with blue cloves. They tend to spring up in small patches everywhere. Left unchecked they mix in with your zoanthids colonies and make it hard to resale once they are contaminated. Someone in our local club was asked the same question and there was a link to this article: I decided to give it a try as a dip. Happy to report that this was done in October 2016 and as of February 2017 there is no signs of any blue clove polyps returning. The Mixing: 1gram of the 22% Fenbendazole( Safeguard Dewormer The less than 10lbs dogs one ) mixed in 1 gallon of RO/DI. The Dosage: Dip is 1000ml of tank water and 40ml of solution. Procedure: I have it container floating on the sump to keep temperature. . Leave the frags in the solution for 24-48 hours. Return frag to the Tank: Remove the frag from the solution and give it a good rinse in a seperate container of saltwater. DO NOT ADD THE FRAG BACK TO THE TANK DIRECTLY ! Expectations: The cloves will look withered and the connected tissues will be gone or partially gone. 1 week after placing the frag back in the tank the cloves will dissapear. Lessons Learned: Rinse in saltwater BEFORE returning it to the tank. After dipping the smaller ones for testing, I started dipping all the larger colonies and other live rocks that contained blue cloves. Some of the medication made it into the show tank from not rinsing. I know this to be true becuase I later realized that other areas that have not been dipped yet had dissapeared in the show tank. The only way that could happen is too much medication made it into the system. The after math: Corals that were killed by the medication getting into the show tank. Nice side benefit was all zenia and green star polyps also erradicated. Zenia gone. ORA Vargas Cespitularia Green Star Polyps Other types of clove polyps Green Nepthia Pulsing Leather Finger Leather Corals. Inhabitants that were not effected: All fish, shrimps, urchins snails were fine. Other soft corals such as toadstools, colt coral, and thicker finger corals were fine. Zoanthids, mushrooms, All lps, sps were also fine. Resolution: Did 4 40g water changes within about a two week period and ran carbon. I waited about a month before reintroducing another Green Nepthia that I got from a reefing buddy.
