Care at a glance
Species-specific aquarium care
- Tank: At least 24 in long and 12 in front to back for one adult (adults commonly reach about 2.0 in / 5 cm; the largest recorded was 3.9 in).
- Water: Freshwater.
- Temperature: 72–75°F (range recorded for this species).
- Hardness: 10–25 dGH.
- Layout: An open-water swimmer: needs long, open swimming space with few obstacles.
Calculated from this species' own FishBase record: tank size from its typical adult length and swimming zone, water values from its recorded ranges. The group guide below fills in general care.
Care guide
Species care notes
- Tank: a base of at least 35 × 12 in (roughly 21 US gallons); space needed is rated “large tank”.
- Water: a fairly wide range, from slightly acidic to slightly alkaline, 68–75 °F, pH 6–8, 3–15 dGH.
- Behaviour: temperament peaceful; a shoaling fish best kept in a group of six or more; suited to a community tank.
- Difficulty: Easy (Seriously Fish rating).
Short excerpts from the species profile:
- Setup: “Best maintained in a densely-planted tank and an excellent choice for the carefully-aquascaped set-up.”
- Diet: “Preys chiefly on insects and aquatic invertebrates in nature.”
- Tankmates: “This species is peaceful but will not compete well with larger or more boisterous tankmates.”
- Breeding: “Like many small cyprinids this species scatters eggs randomly, typically among aquatic vegetation, and does not exhibit parental care.”

Danios and rasboras
Applies to most species in this group. Habitat: These Asian fishes occupy habitats ranging from zebra-danio pools and rice paddies to shaded harlequin streams, rocky Devario streams and planted galaxy-rasbora wetlands. [fg159-zebra, fg159-harlequin, fg159-giant, fg159-galaxy]. Individual species can differ, so compare with the species numbers above and the linked sources.
Housing & setup
- Use at least 90 × 30 cm (36 × 12 in) for zebra danios.
- Harlequins require at least 60 × 30 cm (24 × 12 in), shaded planted cover and subdued light.
- Devario aequipinnatus needs at least 120 × 45 cm (48 × 18 in), oxygenated water, moderate flow and a tight lid.
- Galaxy rasboras need dense planting and broken sight lines in at least 45 × 30 cm (18 × 12 in), with gentle sponge filtration.
- Match chemistry: harlequins pH 5.0–7.5, 1–12 dGH; galaxy rasboras pH 6.5–7.5, 5–15 dGH.
Climate & lighting
| Water | 64.4–77°F |
Diet
- Quality flakes or granules sized to the fish.
- Live or frozen Daphnia and Artemia.
- Bloodworms for zebra danios, harlequins and Devario.
- Small sinking foods for galaxy rasboras, which rarely feed at the surface.
Social life
- Keep zebra danios and harlequins in groups of at least 8–10. Galaxy males spar: dense cover and larger groups distribute aggression. Active Devario can overwhelm timid feeders.
Health watch
- Pseudoloma microsporidiosis in zebra danios.
- Pleistophora infection and columnaris can produce similar white lesions in zebra danios.
- Nipped fins among rival galaxy males.

| Wild diet | In the wild, this species preys chiefly on insects and aquatic invertebrates within its habitat. — Wikipedia (community-edited) |
| Behavior | Inlecypris auropurpurea is known as a peaceful inhabitant in most aquariums, but tends to not compete well with larger or more boisterous tank mates, where it can encounter difficulty feeding against more robust species. Similar to most danio species it can be skittish, but this behavior can be reduced by the adding different types of floating plants or maintaining it alongside other open swimming species. — Wikipedia (community-edited) |
| Appearance and size | Inlecypris auropurpurea can grow to a max standard length of around 60 t0 80 mm on average. They sport a bright purple and blue striped coloration, and are sexually dimorphic with mature females being more robust, less colourful, and a little larger than males. — Wikipedia (community-edited) |
| Biology | Inhabits lake with dense aquatic vegetation. — FishBase |
| History and naming | Inlecypris: from Inlé, is a reference to Inlé Lake, Myanmar, in which this species is endemic, and Cypris, a common suffix for cyprinid genera. auropurpureus: originating from the Latin aurum, meaning 'gold', and purpureus, meaning 'clothed in purple' in reference to the Danio's bright striped coloration. It can reach 10 cm in total length. — Wikipedia (community-edited) |
