Larger marine fish in a reef tank have nutritional demands that small prepared foods simply cannot meet. Wrasses, triggers, puffers, groupers, and predatory species need regular access to substantial, protein-rich prey, and a feeding programme that relies entirely on flake or pellet food leaves these fish under-nourished over time, regardless of how frequently they are fed.

Frozen Pacific krill address this directly. Euphausia pacifica are genuinely nutritious marine crustaceans, not a convenience food that trades nutrition for palatability. They are naturally rich in long-chain omega-3 fatty acids, high-quality marine protein, and astaxanthin, the same carotenoid pigment found in copepods that supports the vivid colouration of reef fish fed a varied, marine-origin diet.

These frozen krill come in five individually portioned blister packs at £15.00, sized appropriately for medium to large marine species. They thaw quickly and are immediately palatable to a wide range of fish, making them a practical centrepiece of a feeding routine for tanks housing larger or predatory species alongside the live and liquid foods in the Reefphyto range.

A reef where larger fish are feeding confidently, holding their colour, and showing active natural behaviour is a reef that is working as it should.

Reefphyto has stocked frozen marine foods alongside our live cultures since 2008. If you have questions about building the right feeding programme for your specific fish, contact us directly and we will help you put it together.
