uggg...I have Aiptasia Anemonies

[Bifferwine]

Not to mention, they kill all your other corals (and can even kill fish, some people have observed). Aiptasia will wipe out thousands of dollars of corals in no time flat. They are pests.

They are the dandelion of the reef tank. At first they seem pretty, then they take over and ruin everything. In the end you will realize that they need to be controlled.
