What are majano anemones?
Scientific name: Family- ActiniidaeSpecies: Anemonia manjano
Common names for the Anemonia majano are Majano Anemone, Anemonia Majano, and Manjo Anemone.
There are two main anemone hitch-hikers on live rock that reef aquarist are most likely to encounter. The first is the Aiptasia sp. Anemone and the second is the Manjano Anemone. It is important to be able to distinguish between the two anemones because the method of anemone removal in this article is not very effective on aiptasia.
The Manjano anemone is also considered a ‘pest' and is equally capable of out-competing and overwhelming other inhabitants in the reef tank. Like the Aiptasia Anemone, it has a pedal column with a sticky foot that is used to attach itself to the rock surface and an oral disk surrounded by tentacles. The color is typically greenish brown to tan with the tentacles having white or light tips. This anemone can grow up to 3 cm (1.5 in) in diameter.
The main difference between the Manjano anemone and the Aiptasia anemone is that the tentacles of the Aiptasia are typically slender and very pointed at the tips, while the Manjano anemone has ‘stubby' tentacles that are often bulbous at the tips.
