PE Mysis Shrimp – Premium Frozen Fish Food (16 oz Flat Pack)

Serious Nutrition for Serious Systems. The Ultimate Bulk Value.

Maximize your feeding efficiency with the Piscine Energetics (PE) Frozen Mysis Shrimp 16 oz Flat Pack. A favorite among professional aquarists, breeders, and hobbyists with large display tanks, this bulk 1-pound slab delivers the same world-renowned nutritional quality in a format designed for heavy usage.

Harvested from the deep, glacial waters of Lake Okanagan, these freshwater Mysis relicta are naturally gut-loaded with phytoplankton and flash-frozen alive. This process creates a bio-encapsulated "superfood" that is cleaner than other frozen foods and irresistible to fish. Whether you are feeding a 200-gallon reef or a breeding system, the 16 oz flat pack ensures you always have premium food on hand.

Why Choose the 16 oz Bulk Flat Pack?

• Superior Value: Get more for your money. The 16 oz pack offers a significant cost-per-ounce savings compared to blister packs or smaller flats, making it the smartest choice for daily heavy feeding.

• Ideal for Large Systems: Perfect for aquarists with predatory fish (like Groupers, Triggers, and Puffers), large schools of Anthias, or multiple aquariums.

• Custom Dosing: The solid slab format puts you in control. Easily carve or break off large chunks for big fish or shave off smaller amounts for precise feeding—no pre-sized cubes to limit you.

• Unmatched Purity: Because PE Mysis are freshwater shrimp, they are naturally low in sodium. This makes them a safe, hydration-friendly food for marine fish that helps minimize osmotic stress.

• Eco-Conscious: PE Mysis is an invasive species in its source lake. By feeding your tank, you are actively helping to restore the ecosystem of Lake Okanagan and support native Salmon populations.

Feeding Instructions

1. Portion: Using a knife or by hand, break off a portion of the frozen slab appropriate for your system's bioload.

2. Thaw: Soak the frozen chunk in a container of aquarium water until fully thawed.

3. Rinse (Optional): PE Mysis is naturally oily (rich in fatty acids). For the clearest water, you may rinse the thawed shrimp in a net with RODI water before feeding.

4. Broadcast Feed: Pour into high-flow areas of the tank to stimulate a chase response.

5. Clean Up: Ensure all food is consumed within 2-3 minutes to maintain water quality.

Expert Tip

For an extra nutritional boost, add a few drops of a liquid vitamin supplement or garlic extract to the thawing water. The sponge-like nature of the whole Mysis shrimp will absorb the enrichment, delivering it directly to your fish's gut!
