Food & nutrition
What is the best food for discus?
A combination of 40% premium pellets (Tropical D-50/D-Allio Plus, Hikari Discus Bio-Gold, Tetra Discus, Sera Discus Granules) + 30-40% homemade beef heart mix + 20-30% frozen food (brine shrimp, krill, bloodworms). No single product — variety makes the difference.
Read the full guideCan I feed beef heart to fry?
Under 5 weeks: NO. Only brine shrimp nauplii + micro-pellets. From 5-8 weeks: only a very fine paste, alongside brine shrimp. Normal-sized pieces = lethal intestinal blockage.
Read the full guideHow do I hatch brine shrimp at home for fry?
2L warm water (28°C) + 60g coarse non-iodized salt (30g/L) + 1 teaspoon of brine shrimp eggs, strong aeration + 24h light. Harvest with a 100 micron net. Cost ~3-5 €/month for 50 fry.
Read the full guideWhy should I avoid live tubifex?
Live tubifex = the #1 source of Hexamita outbreaks, flukes and heavy-metal contamination. 30-60% mortality within 2-4 weeks. Use frozen bloodworms or culture white worms (Enchytraeus) at home.
Read the full guideHow much does food cost per month for 6 adult discus?
~140 RON/month for a complete diet: premium pellets (~30), 1kg homemade beef heart (~40), 200g frozen brine shrimp (~25), 100g krill (~20), 100g bloodworms (~15), amortized supplements (~10).
Read the full guideHow do I intensify discus colors through food?
Natural astaxanthin from Antarctic krill (~300-500 mg/kg dry) + spirulina + carotenoids (paprika, red pepper). 1-2 meals/week with krill + spirulina integrated into the beef heart mix gives a visible boost in 4-6 weeks.
Read the full guideMy Stendker discus refuse pellets — what do I do?
Stendkers are used to Stendker Original Granulat + frozen GoodHeart at the farm. A 4-8 week protocol: order Stendker Original Granulat (~43-89 RON), then a slow transition to Tropical D-50 or Hikari. Tricks: soaking in beef heart juice, a 24h fast, 30°C temperature.
Read the full guideShould I fast my discus one day a week?
Yes, it's mandatory. A 24h fast (Sunday recommended) cleans the digestive tract, prevents fatty liver, stimulates autophagy. Strict — not a single cube. Exceptions: fry under 3 months, breeders in conditioning, sick fish.
Read the full guideCan I combine frozen food with live food or pellets?
Yes. The ideal weekly combination: 40% pellets + 30-40% beef heart mix + 20% frozen (brine shrimp, krill, mysis) + 10% live food occasionally. In the same meal: frozen + pellets OK. On different days: live food or beef heart. Avoid mixing multiple frozen types at once — discus become picky.
Read the full guideHow do I correctly thaw frozen food?
Put the cube in a glass of aquarium water (28-30°C), wait 3-5 min, drain the red liquid (it pollutes the water), then feed. NEVER: microwave, hot water, thawing on the counter, or refreezing.
Read the full guideHow long can I store discus food: pellets, beef heart, frozen?
Opened pellets: max 6 months cool + dry (then 40-60% vitamin oxidation). Frozen beef heart mix: max 3-6 months at -18°C airtight (beyond = rancid fats). Commercial frozen food (blisters): 12-18 months sealed, max 60 days after opening. Liquid supplements: 6 months refrigerated after opening. Optimal storage: airtight Tupperware containers, a cool dry place, darkness, date labeling.
Read the full guideWhat vitamins and supplements should I give discus?
MANDATORY with homemade beef heart: JBL Atvitol (~35-50 RON, 3-5 drops/100g, 2×/week) + spirulina powder (~50-120 RON/250g, 1 tablespoon/kg of mix). OPTIONAL: fresh garlic (appetite stimulant + antiparasitic), astaxanthin/krill (red intensification), vitamins D3+E (breeders). NEVER: human vitamins (Centrum etc.) — TOXIC copper/zinc. Budget: ~50-80 RON/year for a complete setup.
Read the full guideHow do I correctly store pellets and supplements to preserve the vitamins?
Pellets: airtight Tupperware container + silica gel, a cool place (15-22°C), DARKNESS, away from perfumes. NOT in the fridge (condensation). Liquid supplements: fridge at 4°C after opening, sealed lid, darkness. Powder supplements: airtight container, darkness, dry, cool place. Monthly check: smell (rancid = throw out), color (changed = throw out), visible mold (throw out). Oxidized vitamins (invisible) = zero effect on the fish.
