16-26°C, pH 6.0-8.0, 1-12 dGH (Seriously Fish). Undemanding in water chemistry and comfortable at moderate temperatures.

Aquarium

Seriously Fish suggests an 80 x 30 cm footprint. Heavy planting and a dark substrate bring out its colour. An accomplished jumper that slips through small gaps, so fit a tight lid.

Tank Mates & Compatibility

Very peaceful; suits small cyprinids, tetras, livebearers, rainbowfish and loaches. Keep eight to ten or more to calm it and spread dominant males' aggression.

Diet & Feeding

Unfussy: prepared food as the staple plus small frozen or live bloodworm, Daphnia and Artemia for the best colour.

Breeding & Egg-laying

An egg scatterer with no parental care. A few fry may appear in a planted tank, but for more, spawn fish over mesh in a small container so eggs fall out of reach.

7 things to know before welcoming a Glowlight danio

1. 1Keep them in a group

   Glowlight danios settle down when kept in a shoal of 8–10 or more, which also spreads out aggression from dominant males. In small groups, weaker fish may get their fins nipped, so bring home a larger group and provide hiding places.

2. 2Small, up to 3.1 cm

   The maximum standard length is 3.1 cm (FishBase), so this fish is easy to start with in a compact tank. Because the shoal swims actively, a tank with good horizontal length gives them more room to move.

3. 3Peaceful, choose tank mates

   This is a peaceful fish that tends to do well with calm species of similar size. It is safer not to house them with fish that have large mouths or aggressive temperaments.

4. 4Use a tight lid

   Danios can jump out of the water when startled, so a lid on the tank gives peace of mind. Also take care not to leave gaps during water changes and cleaning.

5. 5Food for a small mouth

   Their mouths are small, so choose fine granules or crushed flakes that are easy to swallow. Uneaten food can degrade water quality, so feed only what they finish and remove any leftovers.

6. 6Acclimate slowly

   Changes in temperature and water quality can be stressful right after arrival. Float the bag in the tank to match the temperature, then mix in tank water little by little. For the first few days, feed lightly while you watch how the fish are doing.

7. 7Water quality and daily checks

   Even a hardy fish can become unwell when water quality declines. Do regular water changes, and at feeding time check for anything unusual, such as white spots on the body or changes in the way they swim.
