Superfish freeze-dried daphnia (water fleas) are an excellent natural source of fiber and promote healthy fish digestion. Thanks to their small size, daphnia are ideal for almost all tropical fish. Freeze-drying perfectly preserves all nutrients and eliminates pathogens, making it a safe and nutritious food! Give your fish what they eat in the wild by combining freeze-dried food with their regular daily food to provide them with a varied diet.
