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 an ice blue cichlid community tank
Give the group a stable, planted 190 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 an ice blue cichlid
Ice Blue Cichlid is aggressive and territorial, so most community fish are unsafe; any tank mate must be large, tough and able to hold its own. It mostly occupies the middle of the tank, so it pairs naturally with species that use the other levels.
Ice Blue Cichlid 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 24–28 °C (75–82 °F), pH 7.6–8.6 and 10–25 dGH. Fish needing very different conditions — coldwater species, or hard-water lovers against a soft-water fish — rarely thrive side by side.
Ice Blue Cichlid is a shoaling fish — stock a group of 5+ 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.
