Care guide at a glance
Dario dario
Description
One of the smallest aquarium fish in the hobby, the males a brilliant scarlet striped with iridescent blue. Tiny, territorial in miniature, and endlessly watchable in a nano tank.
Feeding
Strongly prefers live and frozen foods. Frozen cyclops, daphnia, baby brine shrimp and live microworm. Most specimens refuse dry food entirely.
Compatibility
Best kept alone in a species tank or with shrimp. Males are territorial with one another, so allow one male per 15 cm of tank length with cover between. Far too small and too slow for a general community.
Behaviour and personality
Perches among plants and defends a small territory. Males flare and display constantly at one another.
Before you buy
The main reason people fail with this fish is food - it will usually not eat flake, and starves quietly in a community tank. Budget for frozen or live food.
