this is what i found after doing a search...It seems the species has a high rate of asexual reproduction under favorable conditions. Even one jellyfish accidentally introduced in an aquarium may increase in a population of hundreds within a few months if the conditions are really good. It is also very possible that the polyp stage of the species lives on corals or rocks which may be brought into the aquaria. The polyps may form a dense colony if it is provided with much food. Within a short time the number of polyps may be very large, and the polyps may produce many jellyfish. The jellyfish and polyps will eat Artemia nauplii and copepods.
