Feeding a Discus: carnivore diet, frequency, mistakes
Discus : A delicate carnivore: dedicated discus granules, brine shrimp and beef-heart preparations used in moderation. Several small meals a day, since it eats slowly and gets outcompeted at feeding time.

In short: 15 to 20 cm as an adult, 300 L minimum for a group of 5, very soft water between 28 and 30 °C. A gregarious, shy cichlid that forms a group hierarchy and gets outcompeted at feeding time if too harassed. The most demanding for water quality: very soft, acidic, at 28-30 °C, with an RO unit and frequent water changes essential.
Feeding a Discus: diet and habits
The Discus is a carnivore: live or frozen prey (bloodworms, brine shrimp, daphnia) plus protein-rich granules. It feeds in midwater: serve slow-sinking food, in amounts eaten within two minutes at most — everything else ends up as nitrates.
Frequency and variety
The adult Discus rhythm: one or two micro-feeds daily plus one weekly fasting day, perfectly tolerated — remember that overfeeding is the top cause of degraded water. In a group of 5 or more, check everyone reaches the food: dominants serve themselves first. Alternate dry, frozen and rinsed thawed prey across the week.
The costly mistakes
The Discus “begging” at the glass is not starving — it has simply learnt your silhouette: hold the two-minute line. Budget flakes crumble and pollute: serious-brand food costs a few euros more per year, not per month. The rest of the profile is on the full Discus profile.

The guides that apply to you
- Flakes, pellets or wafers: which food should you choose for your fish?
Flakes, pellets or wafers: each shape targets a specific swimming zone. Matching the shape to the species prevents waste and overfeeding.
- Vitamin Supplements for Aquarium Fish: Useful or Marketing?
Vitamin C, oils, immune boosters... are the supplements sold for aquarium fish actually necessary alongside a varied diet?
- Does an overfed fish get slower on the uptake? A study on obesity and memory in zebrafish
Overfeeding is usually framed as a water-quality problem. A study on zebrafish shows it also carries a direct cost to the fish's own learning and memory abilities.
