Aquarium Co-Op Freeze Dried Brine Shrimp is a great treat for almost any community fish. The brine shrimp are gut-loaded with healthy nutrients and freeze-dried into an easy-to-feed cube. When placed in water, the cubes rapidly hydrate and separate out. Fish find them irresistible to eat because they are as close to live baby brine as you can get in a dry food. We love freeze-dried foods as a convenient food to feed because they don't need to be frozen and can sit right near the tank for a quick treat.
