Dr. Bassleer BioFish Food Fuco – Fucoidan Granules for Freshwater & Marine Fish

A brown-algae compound your fish rarely get — but benefit from.

Keepers chasing long-term fish health want functional ingredients backed by real science, not just marketing.

Dr. Bassleer BioFish Food Fuco is a dedicated premium food (freshwater and marine) built around fucoidan, a bioactive compound from brown algae studied for its regenerative and health-supporting properties. German-made functional granules, no artificial colors or fillers.

Fuco is functional health food, not ordinary fish food. It was developed by fish-health expert Dr. Gerald Bassleer, drawing on more than 40 years of experience, and is made in Germany by Aquarium Münster. Each granule is coated after production at low temperature with natural functional additives — probiotics, prebiotics, and plant-based phytobiotics — with no artificial colors or fillers, so nutrition becomes a fish's first line of defense against disease.
