What are they???

[glennemo]

Hello all. I picked up one of theese as a hitchhiker with my pulsing zenia. They have poped up all over my tank. They grow very fast. They are kinda drab brown and tend to overpower any colony that they pop up in. KInda look like mushrooms with long stalks and long tentacles.

aiptasia, kill them.

Aiptasia. A pest anemone that will spread faster than your xenia. Search on here for various methods to kill them, but get them before they spread (more).

Thanks for the quick reply guys. Figured they couldn't be a good thing if they grow and spread that fast. How effective are Berghia Nudibranch and where can I get them?

[aecasasus]

Aiptasia-X works pretty good on them!

You can also get a half dozen or so of peppermint shrimp.
