Well VM, if you like the look of them the good news is they're much less hardy than Aiptasia/Mojano. If you hit them with Joes Juice, Kalkwasser, AiptasiaX, etc they usually do not come back.
Sadly they're often mis-labeled and sold as corals when they're clearly an anemone species. If you ask me, a lot of distributors konw this but still sell them anyways.
