Aptasia

[justinl]

I personally don't recommend buying berghia nudis unless you actually know what to do with it once it has eaten all your aiptasia... and it will, and promptly starve shortly after. You also have to nudi-proof your entire tank so it doesn't get chopped up or stuck in an intake, which is just a pain. There are cases where it's perfectly suitable for using a berghia, but such cases are few and far between.
