my experience is that if they make it through a few months without dissolving into goo, then you have as good a chance as with any other anemone. Brine shrimp are not enough. They need to be fed with small fish (silversides, buy the IQF, not the ones frozen into a block), and you can try other small whole fresh seafoods- shrimp, clams etc. (I only feed mine with silversides or fresh anchovies). There are loads of threads here about keeping these guys. do a search for "ritteri" or "magnifica" and do some reading. Lots of it is very depressing, can't be done stuff, but there are also people who have been quite successful with them. good luck with it
