Feeding a Zebrafish (Danio): Meal Frequency and Mistakes to Avoid
Published by Planète Pets · managing editor: Clément Lacaille · how our guides are written
Short answer: two small meals a day, a pinch of flakes or micro-pellets eaten by the shoal in under two minutes, comfortably cover the needs of an adult zebrafish (danio). A study by Lawrence published in 2007 in Aquaculture (see the study), a reference on the husbandry of this heavily studied laboratory species, notes that the danio is an opportunistic fish with a fast metabolism that accepts a wide range of foods without any complicated special needs. Find our other pointers in the food section and on the fishkeeping hub.

What type of food suits a danio best?
Good-quality flakes or micro-pellets form a sufficient base, supplemented once or twice a week with small live or frozen prey such as brine shrimp or daphnia, which stimulate its natural hunting behaviour at the surface and in open water.
How many meals a day and how much?
Two meals spaced through the day, each fully eaten in one to two minutes, avoid the overdosing that this very lively, always food-seeking fish easily tempts its owner into. This principle echoes what's already covered for overfeeding fish in general.
What's the most common mistake with this social fish?
Feeding a group that's too small or poorly spread through the tank means the fastest individuals grab most of the flakes before the shyer ones get a chance to eat, an imbalance more common in a shoal of fewer than six danios. Scattering the food over the whole surface rather than in one spot fixes this problem.
Should you vary the diet even for such a simple fish?
Yes, alternating flakes, micro-pellets and live or frozen prey limits long-term deficiencies, a principle already useful for varying fish food regardless of the species kept.
- Two meals a day, eaten in one to two minutes, are enough for an adult danio
- Flakes or micro-pellets as a base, live or frozen prey once or twice a week
- Scattering food over the whole surface stops the fastest fish grabbing it all
- A shoal of at least six individuals limits excessive feeding competition
Frequently asked questions
Can a danio go two days without eating?
Yes, no problem, this hardy fish easily copes with an occasional two-day fast, for example during a short absence.
Do danio fry need different feeding?
Yes, fry need microscopic prey such as infusoria or freshly hatched brine shrimp nauplii, too small for an adult fish.
Do danios eat their own eggs after spawning?
Yes, this is common behaviour in this species, which is why a dedicated breeding tank with a separating grid is often recommended.
