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 silver cichlid community tank
Give the group a stable, planted 280 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 silver cichlid
Being semi-aggressive, silver cichlid can nip or harass smaller, slower or long-finned fish — give it space, broken sight-lines and similarly robust companions. It mostly occupies the middle of the tank, so it pairs naturally with species that use the other levels.
Silver Cichlid grows to about 30 cm, so avoid tank mates small enough to be seen as food — as a rule of thumb, skip anything under roughly 15 cm. Match its water, too: aim for 24–28 °C (75–82 °F), pH 7–8 and 5–20 dGH. Fish needing very different conditions — coldwater species, or hard-water lovers against a soft-water fish — rarely thrive side by side.
Silver Cichlid 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.
