Freeze-dried mysis shrimp are small freshwater shrimp (often called “opossum shrimp”) that have been preserved to retain nutrients while being shelf-stable. A protein-focused diet for feeder insects and isopods. They’re also a high-protein, highly palatable food used across aquatics and some reptile/amphibian setups.

What they’re good for

• Fish: Great for bettas, guppies, tetras, cichlids, and many marine species
• Amphibians: Frogs/newts will take them readily
• Reptiles (occasionally): Small aquatic or semi-aquatic species
• Isopods 

Nutritional profile (typical)

• Protein: ~60–70%
• Fat: ~8–12%
• Fiber/Ash: low
• Naturally rich in omega fatty acids → supports coloration and growth
