apesito or whatever.. dont remember the name. So i couldnt do a search on it. I remember seeing a post on how to kill them. Somthing about lemon juice injections? Can anyone verify and tell me the solution?
Looks like an Aiptasia to me. You can kill them by injecting them with kalkwasser paste, some people use a dilute solution of sodium hydroxide, a dilute solution of acid, or buy a commercial product called Joe's Juice.
For the kalk to work best, don't touch the aiptasia with the syringe... just let a glop fall from the end (no needle) and land on the anemone's tentacles... it will retract and carry the kalk paste in with it.
