Tetra Discus, 15 g is a staple granule food for discus from the German brand Tetra. The colour, composition and shape of the granules are tailored to discus: the granules sink slowly into mid-water, where these fish like to feed. According to the manufacturer, the food contains a complete set of vitamins, nutrients and trace elements, and supports natural colour, vitality and disease resistance.

How to feed
Feed discus several times a day in small portions — as much as they'll eat in 2–3 minutes. The granules sink slowly, so discus feeding in mid-water can catch them. Siphon out any uneaten food after a few minutes: discus are sensitive to water quality, and leftover food quickly raises ammonia and nitrite. Introduce a new food gradually, mixing it with the usual one. General feeding rules are covered in aquarium fish food: how to feed.
A varied diet
Granules work well as the base of the diet, alternated with other foods for variety — flakes, tablets and colour-enhancing foods. The manufacturer stresses that granule food is safer than frozen food, as it doesn't bring pathogens into the tank. If you're just starting out, read an aquarium for beginners, and for cycling the biofilter, bacteria help — see our Rikka AQUA START review.
Water and discus health
Even the best food won't help if the water is poor: discus need warm, clean, soft water and regular water changes. Overfeeding is a common cause of trouble — excess food goes uneaten, rots and poisons the water. If your fish darken, hide, refuse food or develop white spots, check the water parameters and start treatment if needed — see our Rikka ICHTHYOCID review for parasite treatment.

Verdict
