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

Ocean Nutrition Frozen Krill Superba is marketed as a market-leader for consistency and traceable sourcing, with a focus on delivering a steady nutrient profile well-suited to the dietary needs of reptiles and amphibians. Although it often sits at a higher price point than budget brands, Ocean Nutrition’s scale and technical sourcing give it an edge in uniformity and supply reliability compared with smaller brands, and it typically offers a more specialized krill option than generalist brands like San Francisco Bay or convenience-focused products like V2O.

Ocean Nutrition Frozen Chopped Shrimp is a convenient, chopped-format product designed for precise portioning and minimal waste for small reptiles and amphibians. Its chopped form and cost-efficient packaging make it a practical alternative to whole shrimp, offering ease of feeding similar to San Francisco Bay Brand but with a stronger focus on portion control and frozen stability. Compared with the premium krill and mysis options, Ocean Nutrition emphasizes convenience and affordability for routine feeding schedules.

Hikari Bio-Pure Frozen Mysis Shrimp is a premium, hygienically processed mysis product prized for consistent size and a high protein/fat profile, making it a strong choice as a nutritious frozen crustacean feed for reptiles and amphibians. Compared with others on this list it commands a higher price but delivers lower bacterial load and a more stable nutrient profile, which is a technical advantage for sensitive amphibians or animals that require a reliable substitute when frozen amphipods/isopods are unavailable.

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.

Exo Terra Vacuum-Packed Silkworms lead the market for premium silkworm offerings by using vacuum-seal packaging that preserves moisture, texture, and shelf life better than standard frozen packs. They command a higher price than common crickets or BSFL but provide superior freshness and minimal freezer-burn risk, making them the go-to for keepers prioritizing live-like feeding quality for delicate amphibians and insectivores.

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.
