    • Splashing Tetra is bite-sized to a 90 cm predatory clown knifefish — it will be eaten.
    • Clown Knifefish is aggressive and may chase or nip the smaller Splashing Tetra — plant heavily and break up sight lines.
    • Your 75 L tank is below the ~750 L this pairing really wants — crowding raises aggression.
    • Keep Splashing Tetra in a shoal of 6+ or it gets stressed and nippy.
  • Fire Eel⛔ Not recommended
    Semi-aggressive · 100 cm · Medium care · 24–28 °C (75–82 °F)
    • Fire Eel (100 cm) is big enough to swallow the 8 cm Splashing Tetra whole.
    • Fire Eel clearly outsizes Splashing Tetra and is semi-aggressive; risky unless the tank is big and well-planted.
    • Your 75 L tank is below the ~380 L this pairing really wants — crowding raises aggression.
    • Keep Splashing Tetra in a shoal of 6+ or it gets stressed and nippy.
  • Koi⛔ Not recommended
    Peaceful · 90 cm · Medium care · 4–28 °C (39–82 °F)
    • Splashing Tetra is bite-sized to a 90 cm koi — it will be eaten.
    • Your 75 L tank is below the ~3800 L this pairing really wants — crowding raises aggression.
    • Keep Splashing Tetra in a shoal of 6+ or it gets stressed and nippy.
  • Redtail Catfish⛔ Not recommended
    Aggressive · 120 cm · Hard care · 24–27 °C (75–81 °F)
    • Redtail Catfish (120 cm) is big enough to swallow the 8 cm Splashing Tetra whole.
    • Redtail Catfish clearly outsizes Splashing Tetra and is aggressive; risky unless the tank is big and well-planted.
    • Your 75 L tank is below the ~5700 L this pairing really wants — crowding raises aggression.
    • Keep Splashing Tetra in a shoal of 6+ or it gets stressed and nippy.
  • Spotted Gar⛔ Not recommended
    Aggressive · 90 cm · Hard care · 18–26 °C (64–79 °F)
    • Spotted Gar (90 cm) is big enough to swallow the 8 cm Splashing Tetra whole.
    • Spotted Gar clearly outsizes Splashing Tetra and is aggressive; risky unless the tank is big and well-planted.
    • Your 75 L tank is below the ~600 L this pairing really wants — crowding raises aggression.
    • Keep Splashing Tetra in a shoal of 6+ or it gets stressed and nippy.
  • Wels Catfish⛔ Not recommended
    Aggressive · 300 cm · Hard care · 15–25 °C (59–77 °F)
    • Size gap is too large (300 vs 8 cm): Wels Catfish will treat Splashing Tetra as food.
    • Wels Catfish clearly outsizes Splashing Tetra and is aggressive; risky unless the tank is big and well-planted.
    • Your 75 L tank is below the ~20000 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 splashing tetra 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 the right tank mates for a splashing tetra

As a peaceful species, splashing tetra 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.

Splashing Tetra grows to about 8 cm, so avoid tank mates small enough to be seen as food — as a rule of thumb, skip anything under roughly 4 cm. Match its water, too: aim for 22–28 °C (72–82 °F), pH 6–7.5 and 2–12 dGH. Fish needing very different conditions — coldwater species, or hard-water lovers against a soft-water fish — rarely thrive side by side.

Splashing Tetra is a shoaling fish — stock a group of 6+ 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.
