Often confused with young bubble tips,they have strong stings and don't play nice with other corals and fish in most cases. They use venomous cells called nematocysts found in their tentacles to sting corals and fish. They can be a challenge to get rid of once established and have been known to take over a reef aquarium by quickly reproducing while stinging and killing other tank invertebrates in the process.
Just Like an Aiptasia, the Majano Anemone is a hitchhiker often brought in on live rock. The best way to avoid getting them in an aquarium is to use a quarantine tank. Place all new live rock, as well as every fish you bring, into a quarantine tank for observation and care before introducing them into your main tank.
Electrocuting them with a wand, injecting them with Kalk made into a paste are effective ways to eliminate them
