Great for aiptasia control, only a half dozen of these tiny guys in stock. Approx. 0.25"

In my experience they do not do well in shipments so be prepared to try several times.
If they make it alive at your system, they are the best solution, how ever if you have any wrasses in your tank they will eat them.

Did you try Aiptasia x by redsea? As far as I know the will kill majano as well.
