Red Finned Danio

A small danio with intense red-orange fins and dark flank stripes or spots.

This trade name refers to a colour presentation of Danio kyathit, whose flank pattern can range from broken stripes to spotting.

This record describes a captive form of the accepted species. Some fish sold as Red Finned Danio may represent an unidentified trade form rather than typical Danio kyathit. Confirm provenance before presenting the identification as certain.

Adult females are generally fuller-bodied and slightly larger. Mature males are usually slimmer and show stronger colour, especially during courtship.

Aquarium information for this uncommon species is limited, so conservative husbandry and careful observation are advised. Keep a group of at least 8 in an aquarium at least 90 cm long.

Provide open swimming space, secure cover, efficient filtration, and strong but broken-up water movement. Use plants, wood, and rounded stone around the margins while preserving a clear central swimming area.

Direct the current through open water but leave calmer pockets behind plants, wood, or stone so every fish can rest without being forced against the flow.

Red Finned Danio is a social, active schooling fish that should be maintained with its own kind. Most chasing is part of normal group interaction, but cramped quarters or a group that is too small can concentrate aggression.

Maintain at least 8, preferably 12 or more. A larger group produces more natural schooling and spreads chasing. Not truly territorial, although males may spar or defend short-lived display positions within the group.

Choose peaceful, similarly active fish that share the same temperature and water requirements. Very slow, timid, or long-finned tankmates may be stressed by constant movement or persistent feeding competition. Small shrimp and shrimplets may be eaten.

Keep the water clean and oxygen-rich. Soft to moderately hard water is preferable, with no sudden chemistry changes.

A small, colourful danio that picks food from midwater. Offer fine flake and frozen daphnia.

Feed small portions once or twice daily. Active danios feed quickly, so check that slower tankmates receive food.

An egg-scattering spawner with no parental care. Condition adults well, then use fine-leaved plants, spawning mops, mesh, or marbles to protect eggs from the adults. Remove the breeders after spawning and raise the fry on infusoria or very fine prepared food before moving to microworms and Artemia nauplii. For uncommon species, keep detailed notes on temperature, timing, adult condition, and fry growth because dependable species-specific aquarium reports may be limited.
