Optimal nutrition
Varied food kit for discus
A varied diet for vibrant colours, optimal growth and long-term health.
The right diet: the secret to vibrant colours
Discus fed only pellets look acceptable. Discus fed a varied diet look spectacular. The difference isn't genetic — it's at the table.
An ideal typical routine: premium pellets in the morning, frozen food at noon (brine shrimp, blackworms), pellets or beef heart in the evening. Vary it weekly so the fish get all the necessary amino acids and vitamins.
Beef heart: yes or no?
Beef heart is controversial. Pro: concentrated protein, helps fast growth. Con: it pollutes the water heavily and contains animal fats that can make the fish fat.
Recommendation: use beef heart 2–3 times a week, not daily. And use homemade recipes with vegetables, not just pure meat.

Clear steps: from box to your first discus
- 1Buy premium pellets as the base (60–70% of the ration) and varied frozen food as the rest.
- 2Portion the beef heart into 5–10g bags and freeze — you avoid repeated thawing.
- 3Thaw frozen food in a little tank water 10 minutes before feeding.
- 4Add liquid vitamins (Sera Fishtamin) on the pellets once a week.
- 5Feed adults 2–3x/day, fry 4–5x/day — small amounts, no surplus.
- 6Record what foods you give and how the fish react (appetite, colour, faeces) for 4 weeks.
Common mistakes to avoid
- Only pellets, no frozen food — washed-out colours, slow growth, lack of vitality.
- Beef heart daily — it makes the fish fat and pollutes the water fast.
- Large amounts of food not eaten in 2–3 minutes — the main cause of nitrate problems.
- Un-thawed frozen food — local thermal shock and risk of digestive problems.
- Ignoring the faeces — white or stringy faeces indicate digestive problems or parasites.
- Lack of variety — discus fed monotonously develop nutritional deficiencies within months.
Frequently asked questions
How many times a day should I feed discus?
Adults: 2–3 small meals a day. Fry and subadults: 4–5 meals a day for optimal growth. Never give more than they can eat in 2–3 minutes.
Can I keep discus on pellets only?
Yes, they survive, but they won't have optimal colours and vitality. Variety makes the major difference in long-term appearance and health.
