General Information: Active little Tetra characterised by the bright orange colour along the spine and above the eyes that shines or glows when the tank lights are on (hence the common name).
Tank Requirements: Planted, with some open swimming space. Whilst these fish can do well in slightly alkaline water, they display at their best in pH 7 or below.
Diet Requirements: Omnivorous. Will eagerly take anything offered. Include a vegetable component. Regular live foods will improve colour.
Compatibility: Peaceful. Fine in community. Keep with other peaceful species.
Recommendations: As with all Tetra, these should be kept in a group of 6 or more. 10 individuals would make a stunning display.
Common Problems:
Similar Species: Other Tetra and Characins.
Sexing: Males are generally smaller and slimmer than the females.
Breeding: Relatively easy in a separate breeding tank furnished with moss/spawning mops and reduced alkalinity/hardness (pH 6 and gH below 5). Remove adults after spawning and darken tank until free swimming.

 Re: Glofish?

No, don't worry, these are a naturally occurring species You might also see glowlight danios (Danio choprae) which are similarly natural. We wouldn't be providing caresheets on dyed fish or GM fish - the former is a vile and cruel practice, and import of GM fish into UK remains illegal.
