It's my understanding that frozen brine is just garbage, but live brine is OK, but made even better with the addition of Zoe phyto etc... I feed my fish live brine soaked in Zoe twice a week. It's a good dose of vitamins and kind of a nice treat. If you are looking to set one up in your display I would not. Brine water can get loaded with trates, and fowl your water. If you do decide to breed try mysis, a lot more nutrients in those little boogers.
