I read and article , about large aiptasia, they are not touched by the shrimps just played with. So the technique the guy used; is to pull then off. I know , they'll return of course but they'll be small enough for the shrimp to get at them. His article when on saying its a constant battle once you get them. You see ; the shrimp when it eats them , it cuts them in small pieces, so some will return. the article when on saying its the shrimp way of surviving it eats only the small one so it make sure it has a constant supply of it , but small ones. One misconception of the aiptasia, is that it has eggs. Wrong, it has filament its leave while moving from place to place. yes it moves, and as it does, it leaves these filaments with reproducing cells, creating new ones as it moves or if its broken. The shrimp you see knows this and make sure it has futur food. So if you buy shrimps to get rid of it. They will for a while . But you must keep the shrimp, to controle the incomming generation of aiptasia. So if your shrimp dies , replace her quick. If your going to use hot water or vinegar or salt water you must aim at the foot, to cause osmosis imbalance and get all the cell in the body. The chemical works if the mouth is targeted, but must be repeated if she reapears within afew days, it must consume enough of it to die. The glue well never used that technique and it didn't specified. So your shrimp will get the small ones and keep them in check. While this process is slow , get them with the chemical . The combination of both will get the problem under controle. Remember there is no egg, her hole body can regenerate 100 %.
