Dr. Bassleer BioFish Food Forte – Immune-Boost Conditioning Granules

The fitness treatment your fish should get every month.

Even healthy fish hit stress points — illness, a move, new tankmates — and that's exactly when their defenses are lowest.

Dr. Bassleer BioFish Food Forte builds on the Regular formula and adds immune stimulators: citrus fruit pulp, high-quality glucan, yeast, and algae extracts. A 10-day "fitness treatment" every three to four weeks is Dr. Bassleer's recommended way to keep fish resilient — especially during stress. German-made, functionally coated, no artificial colors or fillers.

Dr. Bassleer Forte is functional health food, not ordinary fish food — developed by renowned fish-health expert Dr. Gerald Bassleer, who has spent 40+ years in fish health, and made in Germany by Aquarium Münster. The functional additives (probiotics, prebiotics and plant-based phytobiotics) are coated on after production at low temperature so the beneficial compounds are preserved, and there are no artificial colors or fillers. The guiding idea is simple: good nutrition is a fish's first line of defense against disease.

1. Run a 10-day course of Forte every 3–4 weeks.
2. Lean on it when moving fish, restocking, or after illness.
3. Feed only what's eaten in a few minutes.

Put a fitness routine on the schedule. Add to cart.

Why Dr. Bassleer Forte

• Immune stimulators: the Regular formula plus citrus fruit pulp, high-quality beta-glucan, yeast and algae extracts to support your fish's defenses during stress — designed for a periodic fitness treatment.
• Functional additives: probiotics, prebiotics and plant-based phytobiotics are coated on at low temperature after production, so the beneficial compounds stay intact rather than being cooked away.
• German-made quality: produced in Germany by Aquarium Münster with no artificial colors and no fillers — just functional nutrition.
• Easily digestible, clean water: the granules are easily digestible and low-waste, so they don't cloud your aquarium.

Best For

Tropical and cold-water aquarium fish that need a periodic immune boost — especially around stress points like moving fish, restocking, or recovery after illness. Use Forte as a scheduled conditioning treatment and rotate it into a varied Dr. Bassleer diet alongside your daily staple rather than feeding it as the sole everyday food.

Feeding

Dr. Bassleer recommends running Forte as a 10-day "fitness treatment" every three to four weeks. During a course, feed once or twice daily, offering only what the fish eat within a few minutes, and remove any uneaten food. Choose the granule size (M/L/XL/XXL) to match the mouths of your fish so every one can take it comfortably.

FAQ

Which granule size should I choose? Match the granule (M/L/XL/XXL) to your fish — smaller granules for small-mouthed community fish, larger for bigger cichlids and similar. The guaranteed analysis shown reflects the M granule and varies slightly by size and batch.

Will it cloud my water? No. The granules are easily digestible and low-waste, so they don't pollute or cloud the aquarium when you feed only what's eaten and remove the rest.

How often should I use it? Dr. Bassleer recommends a 10-day fitness treatment every three to four weeks, and leaning on Forte around stress points like moves, restocking or recovery. Between courses, return to your daily Dr. Bassleer staple.
