Fish Science Large Carnivore Diet 570g Sinking Pellets for Oscars, Rays & Catfish

The FS Large Carnivore Diet is a 4.5mm sinking pellet food formulated specifically for large carnivorous freshwater fish — oscars, rays, catfish, and similar species with a natural preference for insect and invertebrate prey. Rather than relying on generic fishmeal bases, this diet is built around whole-prey ingredients that reflect what these fish would encounter in the wild.

Insect-Based Protein Foundation

The formula centres on mealworm meal and earthworm flour alongside herring meal, creating a protein profile that mirrors the varied, high-protein diet large carnivores require. With 43% protein and 11% oil, the nutritional analysis reflects a diet built for the demands of actively growing, predatory fish.

Natural Colour Enhancement

Rather than synthetic colorants, this diet uses Spirulina powder and dried seaweed (kelp) to support natural pigmentation from within. These ingredients contribute to colouration in a way that works alongside the fish's own biology over time.

Immune System Support

The formula includes dried garlic flour, Beta Glucans, and polyphenols — ingredients recognised for their role in supporting immune function. Tocopherol and rosemary are also present as natural antioxidants, helping to preserve both the feed quality and the fish's condition.
