Fisch Ernährungsleitfaden 2026

Fish nutrition varies enormously by species. Herbivorous fish need algae and plant matter, carnivores need protein-rich foods, and omnivores need balanced variety. Overfeeding is the most common mistake in fishkeeping, polluting water and causing health problems.

Überblick über die Ernährungsbedürfnisse

Fish can be carnivores (bettas, arowana), herbivores (plecos, tangs), or omnivores (most community fish). The key rule is to feed only what fish can consume within 2-3 minutes. Uneaten food decomposes, producing ammonia that poisons the tank. Variety is important -- rotating between flakes, pellets, and frozen foods provides complete nutrition.

⚡ Wichtige Nährstoffe

Protein

The primary nutrient for growth and repair. Carnivorous fish need 40-50%, herbivores need 15-30%.

Beste Quellen: Brine shrimp, bloodworms, fish meal pellets

Vitamins

Vitamin C prevents disease; B vitamins support metabolism. Many degrade in stored food.

Beste Quellen: Fresh/frozen foods, vitamin-enriched flakes

Faser

Important for herbivorous fish to prevent bloat and support digestion.

Beste Quellen: Spirulina, blanched vegetables, algae wafers

Carotenoids

Enhance and maintain vibrant coloration in ornamental fish.

Beste Quellen: Astaxanthin, spirulina, shrimp

🚫 Lebensmittel, die zu vermeiden sind

Brot/Cracker

Expands in the stomach, causes bloat, and fouls water rapidly.

Häufig gestellte Fragen

How often should I feed my fish?▼

Most adult fish do well with 1-2 small feedings per day. Fry (baby fish) need 3-4 feedings. The biggest mistake is overfeeding — it pollutes water faster than fish can eat. One fasting day per week is beneficial.

What do I feed bottom-dwelling fish?▼

Bottom feeders like corydoras and plecos need sinking pellets or wafers that reach the substrate. Algae wafers for herbivores, sinking carnivore pellets for catfish. Feed after lights out so other fish don't steal the food.

Can I feed my fish vegetables?▼

Yes! Many fish enjoy blanched (briefly boiled) zucchini, spinach, peas (shelled), and cucumber. This is especially important for herbivorous species. Remove uneaten veggies after a few hours.
