Convict cichlid tank mates

Easy to breed is the headline. The problem is that a bonded pair will overrun your tank and bully every neighbour relentlessly.

Evidence: partially verified
Confidence: high

Lists below are built from this species record (safest, best with, risky, unsafe) — each link opens a pair-level check, not a guarantee.

Best tank mates (on file)

Merged from conservative safest and best with fields — de-duplicated by species.

  • The Convict cichlid profile lists Boesemani Rainbowfish as both safe and a recommended pairing. Boesemani Rainbowfish schools in groups of 6 or more, so plan room for the whole group rather than one fish.

  • The Convict cichlid profile lists Corydoras Catfish as both safe and a recommended pairing. Corydoras Catfish schools in groups of 6 or more, so plan room for the whole group rather than one fish.

  • The Convict cichlid profile lists Electric Blue Acara as a recommended pairing. Electric Blue Acara is a semi-aggressive intermediate-care species with a 150L minimum. Run the pair checker for your specific tank before stocking.

  • The Convict cichlid profile lists Molly as both safe and a recommended pairing. Molly is a peaceful beginner-care species with a 80L minimum. Run the pair checker for your specific tank before stocking.

  • The Convict cichlid profile lists Swordtail as both safe and a recommended pairing. Swordtail is a semi-aggressive beginner-care species with a 80L minimum. Run the pair checker for your specific tank before stocking.

Risky or situational

From risky tank mates and broad avoid with (excluding “unsafe” below). May work with species-only setups, more water, or mature systems — read the pair page.

  • Marked risky or situational on the profile. Tank length and group size change the outcome more than a temperament label does.

  • Both species defend territory. The pairing needs a long footprint and rockwork or planting that breaks the sightline between two defended spots. Run the pair checker before stocking.

  • Both species defend territory. The pairing needs a long footprint and rockwork or planting that breaks the sightline between two defended spots. Betta is rated semi-aggressive, so expect chasing, fin damage, or display behaviour directed at Convict cichlid. Run the pair checker before stocking.

Fish to avoid with Convict cichlid

From the unsafe list — predation, aggression, or space rules on this profile.

  • Convict cichlid is flagged as predatory or as likely to eat small fish, and Chili Rasbora at 2cm is well within an adult Convict cichlid's gape.

  • Convict cichlid is flagged as predatory or as likely to eat small fish, and Guppy at 5cm is well within an adult Convict cichlid's gape.

  • Convict cichlid is flagged as predatory or as likely to eat small fish, and Ember Tetra at 2cm is well within an adult Convict cichlid's gape.

  • German Blue Ram conflicts with Convict cichlid on temperament, predation, or footprint. The juvenile size in a shop tank is not the figure that matters here.

Tank size and groups

  • Published minimum for Convict cichlid: 200L — group minimum 2 .
  • Compatibility changes when the tank is too short for turning, too little for a real school, or too warm for one species and not the other — that is why pair checks include tank context, not only temperament.
  • Nearest litre hub to this minimum: 200L hub.

Easier alternatives to consider

Conservative beginner-peaceful picks from the library — not replacements for reading, but a shorter on-ramp than this species for a first tank.

Plan before you buy

Pair checks for every mix, then multi-species stocking in the builder.

Filtration & heating

A 200L minimum tank for Convict cichlid needs a filter rated for at least 800L/hr turnover and a heater maintaining 2230°C.
