Anemone: Tank threat or not?

[DworsackJem]

Hello, just trying to figure out if these anemones in my tank are invasive or not. With my blue light on they glow greenish and neon and I really like them. Obviously don’t want them in my tank if they are invasive. Thoughts would be great, thanks!

Generally consider to be pests that will take over the tank. Either Majano or all anemone.
