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 clown pleco community tank

Give the group a stable, planted 80 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 clown pleco

As a peaceful species, clown pleco 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.

Clown Pleco grows to about 9 cm, so avoid tank mates small enough to be seen as food — as a rule of thumb, skip anything under roughly 5 cm. Match its water, too: aim for 24–28 °C (75–82 °F), pH 6.5–7.5 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.

Clown Pleco 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.
