  • Amano Shrimp ⚠️ With caution
    Easy care · Peaceful · 5 cm · 18–28 °C (64–82 °F)
    Bolivian Ram may eat Amano Shrimp or pick off its shrimplets — a densely planted tank with moss gives them a fighting chance.

    Your 75 L tank is below the ~120 L this pairing really wants — crowding raises aggression.

    pH preferences only just meet (Bolivian Ram 6.5–7.5 vs Auratus Cichlid 7.6–8.8) — target the overlap and acclimate slowly.

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 bolivian ram 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 bolivian ram

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

Bolivian Ram 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 24–28 °C (75–82 °F), pH 6.5–7.5 and 5–12 dGH. Fish needing very different conditions — coldwater species, or hard-water lovers against a soft-water fish — rarely thrive side by side.

Bolivian Ram doesn't need its own kind to feel secure; think twice before keeping more than one if it is territorial. Whatever you add, introduce new fish slowly, watch for bullying in the first days, and have a backup plan if temperaments clash.
