Common Name: Majano Anemone

Scientific Name: A. majano

Majano are small light brown semi-transparent anemones with green tip coloration, the tips can be bubble shaped or pointy depending on the conditions. The adult anemones have a relatively long slender stock that grows to 5 cm in length with tentacles that can reach the same size. The Manjo Anemone can quickly reach plague proportions in captivity, Corals and other anemones are the most affected by this pest. In the aquarium majano reproduce through the process known as pedal or basal laceration which occurs when the parent anemone wanders around. When trying to get rid of the creatures some aquarists scrape or cut the anemone leaving small bits of tissue, these grow into new anemone. These traits allow the majano anemone to reproduce very quickly and grow to a plague proportions if not treated. Majano as all anemone can sting corals and livestock making it an unwanted inhabitant on the aquarium and luckily there are several useful treatments. The following is good way to check if the critter you are looking at is in fact majano and not some kind of polyp – Poke the thing and if it sucks into the rock, it is likely majano. If it just folds up, it is probably a harmless polyp.

Common Opinion: BAD

Possible solutions:

As noted above, majano reproduce in the reef tank by basal laceration. If you take your frustrations out by trying to maim, chop, cut, scrap or otherwise mechanically torture, kill or remove them, you are basically just propagating them as the tiny left over pieces can grow into new anemones. therefore, DO NOT do the above. Several useful treatments for this problem are available. The most common one is introducing animals into the tank that will eat the majano. Filefish and peppermint shrimp are the most common ones used but Berghia verrucicornis Nudibranch, Raccoon Butterflyfish and Copperband Butterflyfish are reported to eat majano as well. Commercial chemical solutions are also available in most fish stores, be sure to follow the directions on the box. If all the above is not available,  boiling aquarium water in the microwave and squirting the hot water into and around the creature to boil it completely sometimes helps aswell.
