Top 7 Frozen Invertebrates for Reptiles & Amphibians in the United States (2025) — Expert-Backed Choices for Nutrition, Convenience, and Sustainability

Omega One Frozen Super Krill is valued for a nutrient-forward profile and a mid-market price that balances quality with cost; it is often chosen by keepers seeking higher natural oil content without the premium price of specialty suppliers. Technically competitive with Ocean Nutrition on lipid content and more refined than basic budget brands such as San Francisco Bay, Omega One offers a good compromise between the premium consistency of Hikari and the portioning convenience of cube formats like V2O.

V2O Frozen Mysis Shrimp occupies the specialty nutrition niche with mysis shrimp prized for higher lipid and natural omega content, making it especially attractive for aquatic amphibians and carnivorous reptiles that need energy-dense feeds. Technically superior in essential fatty acids and palatability, it typically commands a premium but can improve condition and coloration more quickly than plain chopped or mini shrimp. Against the other offerings, V2O is the nutrient-dense, performance-oriented choice for hobbyists focused on growth and breeding outcomes.

PE Mysis Frozen Freshwater Shrimp presents a mid-range option with larger, meatier individuals than brine shrimp and typically undercuts premium brands on price, making it a practical compromise for keepers seeking amphipod-like nutrition without premium cost. It shares many processing advantages with higher-end mysis products but is positioned as the value choice for occasional amphipod/isopod substitution.

Repashy Grub Pie Frozen Blend is positioned as the best-in-class option for frozen insect blends for reptiles and amphibians because it pairs laboratory-formulated nutrient profiles with consistent insect sourcing, giving keepers reliable calcium:phosphorus ratios and predictable feeding outcomes. It commands a premium price compared with commodity mixes like Hagen Exo Terra but offers a technical advantage in standardized fortification and batch testing that reduces the need for ad-hoc supplementation. For owners focused on precise nutrition for growing or breeding animals, Repashy’s transparency and consistency justify the higher cost versus the broader-appeal brands on this list.

The Worm Lady Frozen Hornworms are the specialist pick for hydration-focused feeding and picky amphibians, offering large, water-rich worms with a soft texture that many finicky eaters prefer. They are usually sold at a premium and are lower in calcium compared with products like CalciGrubs or Hikari crickets, so they perform best when used alongside calcium-supplemented or gutloaded staples.

Josh's Frogs Frozen Black Soldier Fly Larvae are marketed as a premium frozen BSF option formulated specifically for reptiles and amphibians, with flash-freezing intended to lock in protein, fat and natural micronutrients. Compared with freeze-dried Fluker’s and mass-market brine shrimp, Josh’s Frogs commands a higher price but offers superior moisture content and palatability that can improve acceptance and growth rates in picky or growing animals.
