Brine shrimp have been compressed into cubes and freeze dried. Cubes are approximately 1/2" square. When dry they can be easily crumbled to make a powdery food for small fish or fry. Or toss the cube in and it will float, fish can pick at it as it rehydrates and slowly falls apart. Everyone seems to like snaking on it including bottom feeders. It can be difficult to break the cubes into smaller pieces without it crumbling.
This product is great for Saltwater fish. It is easy to break up.
Freeze dried is handier than frozen. Fish love it, and if you leave it out all night, it’s still good
Purchased this to give my fish an occasional change of pace. They love it!
My Oscar is a very picky eater but loves these! Great supplement for his pellet diet.
