These come up for sale from time to time (a guy with a permit is allowed to collect an egg carrying male, I think once a year. He returns the male and raises the offspring). Most of them go to public institutions, which spend a large percentage of each day working on feeding them live mysis.
Me, I wouldnt attempt it unless I had a 6 x 6 x 10-15 ft deep aquarium, a massive chiller, and a mysis production system consisting of 6 75 gallon tanks and 7 10 gallon tanks. (not that I have thought about it or anything
)
