    • Wolf Cichlid (72 cm) is big enough to swallow the 4 cm Sparkling Gourami whole.
    • Wolf Cichlid is aggressive and may chase or nip the smaller Sparkling Gourami — plant heavily and break up sight lines.
    • Your 75 L tank is below the ~760 L this pairing really wants — crowding raises aggression.

Compatibility is computed from each species' care data — a strong starting point, not a guarantee. Individual temperament varies, so always introduce new fish slowly and watch them.

Setting up a sparkling gourami community tank

Give the group a stable, planted 75 L+ tank with a gentle filter, a reliable heater and plenty of cover — broken sight lines and hiding spots let mid-water and bottom dwellers keep out of each other's way. Cycle it fully and stock gradually.

How to choose

How to choose the right tank mates for a sparkling gourami

As a peaceful species, sparkling gourami is easily bullied — favour other calm, non-nippy fish and steer clear of boisterous or aggressive tank mates. It mostly occupies the top of the tank, so it pairs naturally with species that use the other levels.

Sparkling Gourami grows to about 4 cm, so avoid tank mates small enough to be seen as food — as a rule of thumb, skip anything under roughly 2 cm. Match its water, too: aim for 24–28 °C (75–82 °F), pH 5.5–7.5 and 2–10 dGH. Fish needing very different conditions — coldwater species, or hard-water lovers against a soft-water fish — rarely thrive side by side.

Sparkling Gourami is a shoaling fish — stock a group of 4+ of its own kind first, then build compatible tank mates around them. Whatever you add, introduce new fish slowly, watch for bullying in the first days, and have a backup plan if temperaments clash.
