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 pictus catfish community tank
Give the group a stable, planted 210 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 pictus catfish
Being semi-aggressive, pictus catfish can nip or harass smaller, slower or long-finned fish — give it space, broken sight-lines and similarly robust companions. It mostly occupies the bottom of the tank, so it pairs naturally with species that use the other levels.
Pictus Catfish grows to about 12 cm, so avoid tank mates small enough to be seen as food — as a rule of thumb, skip anything under roughly 6 cm. Match its water, too: aim for 22–27 °C (72–81 °F), pH 6–7.5 and 5–15 dGH. Fish needing very different conditions — coldwater species, or hard-water lovers against a soft-water fish — rarely thrive side by side.
Pictus Catfish is a shoaling fish — stock a group of 3+ 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.
