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 lima shovelnose catfish community tank

Give the group a stable, planted 760 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 lima shovelnose catfish

Being semi-aggressive, lima shovelnose 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.

Lima Shovelnose Catfish grows to about 50 cm, so avoid tank mates small enough to be seen as food — as a rule of thumb, skip anything under roughly 25 cm. Match its water, too: aim for 23–30 °C (73–86 °F), pH 6–7.5 and 1–15 dGH. Fish needing very different conditions — coldwater species, or hard-water lovers against a soft-water fish — rarely thrive side by side.

Lima Shovelnose Catfish 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.
