Gamma Blister Copepod Frozen Fish Food 100g

The Gamma Blister Copepod 100g is a frozen natural food source suited to a wide range of aquarium fish, including finicky or difficult feeders. Flash frozen at the point of capture and gamma irradiated, it delivers a clean, pathogen-free feed that keeps both your fish and your tank water in better condition.

Natural food, properly preserved

Copepods are a nutritionally dense, 100% natural food that many marine and freshwater fish actively seek out. Flash freezing at capture locks in freshness and nutritional integrity, meaning what reaches your fish is as close to live food as frozen can get.

Gamma irradiation — why it matters

Unlike standard frozen foods, Gamma Blister products are gamma irradiated after freezing. This process eliminates pathogens and parasites without the use of chemicals or preservatives, removing the disease risk that can come with introducing live or untreated frozen foods to your aquarium.

Feeding guidance

The blister can be placed directly into the aquarium, but for better nutrient control it is worth defrosting only the amount needed per feed and straining off the excess water before adding it to the tank. This helps prevent unnecessary organic load building up in the water column.

A straightforward, reliable frozen food for keepers who want a natural diet option they can trust.
