Compatibility brief

Can Ember Tetra live with Glowlight Tetra?

VerdictGOOD

Often a workable match in a suitable, well-run tank. Still verify behaviour in your setup.

In many setups, Ember Tetra and Glowlight Tetra are often kept together in a suitable peaceful community when temperature and pH are matched and the tank is sized for adults. Individual behaviour, filtration, and layout still decide whether it works in your home.

Temperament / behaviour

Both are small peaceful tetras that share midwater and soft-water preferences, so this is a common nano-community mix rather than a risky experiment. They do not need separate territories, and neither species is known for fin-nipping in a calm tank. The limit is school size, especially on the ember side. Glowlights need a real group of six or more, but embers look best and behave most naturally at eight or more. Understocked embers stay pale and shy, which keepers often misread as incompatibility.

Assessment details

  1. Compatible temperaments

    Both Ember Tetra and Glowlight Tetra share a peaceful temperament.

  2. Compatible temperature range

    Both fish can comfortably share similar water temperatures.

Next steps

Concrete changes, not "research more" filler.

  • Keep at least eight ember tetras and six or more glowlights in a planted tank with stable soft water, and feed small foods both schools can reach.
  • Ember Tetra should be kept in a group of at least 8 for best health and behaviour.
  • Glowlight Tetra should be kept in a group of at least 6 for best health and behaviour.

Ember Tetra + Glowlight Tetra — common questions

Can Ember Tetra live with Glowlight Tetra?
Usually yes. Fishori’s verdict is GOOD for mixing these peaceful tetras in soft water. Ember numbers matter more than glowlight numbers; too few embers is the usual limit, not aggression.
What tank size do you need for Ember Tetra and Glowlight Tetra together?
Plan around 60 litres as the working minimum. That figure comes from each species' published minimum and their group needs, and it assumes adult sizes, not shop sizes.
What should you check before buying?
Ember Tetra should be kept in a group of at least 8 for best health and behaviour. Glowlight Tetra should be kept in a group of at least 6 for best health and behaviour.
