L. Wurdemanni Peppermint Shrimp s the specific shrimp that will eat it. Here are the differences as borrowed from the site
www.reefs.org:
L. rathbunae
Variation - There are 2 varieties of L. rathbunae with the most obvious difference being the number of rostral teeth (number of serrations on that
[hr]
).
Habitat - Sometimes from sponges; the typical from generally occurs from 13 to 119 meters but the form with more rostral teeth generally occurs in depths of 9 meters or less.
Known Range - Range of the typical form is SE Cape Fear, NC , east coast of Florida to Yucatan. The range of the form with more numerous rostral teeth is Bermuda, Miami and Venezuela.
L. Wurdemanni
Variation - There are also two forms in this species and they too are most easily differentiated by the number of teeth on the upper margin of the rostrum, the thickness of the second leg, and other stuff.
Habitat - Commonly found on stone jetties or AMONG HYDROIDS growing on piles or buoys, or in sponges. The EMPHASIS is mine but it may provide a clue to the food preferences of this species.
Known Range - Great Egg Harbor NJ to Port Aransas TX; Surinam; French Guiana; Mamanguape and Sao Paulo, Brazil
Remarks - When approached by a spiny boxfish or filefish, this shrimp begins rhythmically rocking to and fro; ascending vertically in a peculiar walking motion, it mounts its ''host'' and begins picking off parasites. The shrimp will swarm over the fingers of a person, picking at cuts and dead skin.
True L. wurdemanni has always eaten Aiptasia IME, but it is fairly localized to their territory, so you need enough shrimp to cover the tank. It is reasonable to suspect that anything that will eat one Cnidarian will eat others as well, and their have been reports of L wurdemanni eating coral. I've not seen that, but I have never kept SPS much.
The picture I have attached is a true L. Wurdemanni shrimp.
Bob Fenner's site agrees with this type of shrimp eating Aiptasia and also suggests Copperhead Butterflies as well as Emperor Angels to help control it.
Joe's Juice is also another way to get rid of it.
This problem can be rid, but it will take work as Steve Pro (an author of an article I recently read) equates Aiptasia as a weed with a sting for sensitive creatures.
