Dr. Bassleer BioFish Food MicroNano – Dust Food for Larvae & Plankton Feeders

Feed the tiniest mouths in your tank — and your reef.

Fish larvae, plankton feeders, and filter-feeding corals need particles so small that ordinary foods simply pass them by.

Dr. Bassleer BioFish Food MicroNano is an ultra-fine dust food made for feeding fish larvae and plankton eaters such as corals and other small filter feeders — the brand's German-made functional nutrition milled to the finest grade, with no artificial colors or fillers.

MicroNano 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. The food 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.

1. Dose a small amount and target where your smallest feeders gather.
2. Feed lightly and often rather than in one big dose.
3. Watch water quality and adjust.

Nourish what nothing else can reach. Add to cart.
