they can eat ghost shrimp as well and usually those are easier to get that live brine. The only thing bad about feeding is that they are pickers and need a good supply of food and need to be fed often. This is from (what I believe to be true) is that they do not have a stomach but some type of diggestive track so they cant hold food for long, they simply eat, take the nutrients from it and then it passes as waste. So from what I THINK this is the reason they are constantly looking for food.
