How big does a zebra danio get?
A zebra danio (Danio rerio) reaches about 2.0 inches as an adult. Plan tank size and tank mates around the adult size, not the small fish you buy at the store.
Tank size & setup
Give a zebra danio a minimum of 10 gallons, with water at 64–77°F and a pH of 6.5–7.5. Keep them in groups of at least 6 — they are shoaling fish and become stressed and washed-out alone. As a easy-care, omnivore species, a stable, cycled tank with the right diet keeps them healthiest.
Good tank mates
Pair a zebra danio with peaceful species that share its temperature and pH range. Compatible options include:
- Neon Tetra — 1.5", 10g min
- Guppy — 2.0", 10g min
- Molly — 4.0", 20g min
- Platy — 2.5", 10g min
- Corydoras Catfish — 2.5", 20g min
