Some fish are more picky when it comes to their food then others. When frozen isn’t working you might try fresh, or live. With the Brine Shrimp hatchery you can do just that. This hatchery keeps everything together in one place. The placement of the airline keeps water from ever entering the air pump. The bottom of the hatchery is convex to draw all of the brine shrimp out. Complete instructions are included as well as an air pump and a fine net to strain the brine shrimp before feeding your tank. All you need is a light. This reactor can also be used for growing phytoplankton and rotifers. The hatchery is 20 inches tall and be bought for a very affordable $30.
