Kribensis tank mates

Kribensis tank mates are a breeding-cave problem first. A bonded pair becomes territorial when fry appear, and the live engine marks no GOOD companions on this hub — bristlenose plecos, cherry barbs, corydoras, Jack Dempseys, mollies, neon tetras, and platies all sit in caution. Oscars are avoid. Midwater dither can work with length, broken sight lines, and a rehome plan for aggression spikes; bottom neighbours still lose caves during spawning. Do not stock a krib pair into a finished nano community and hope the engine finds a safe list — plan the caves and the caution list before the bags.

Common mistakeKeeping kribensis with no cave is how keepers invent a pair that claims any corner and bullies tank mates without pause. Give a designated nest site and plant breaks from day one. Easy to keep is not the same as easy to share a mixed community during spawn.

Risky or situational

May work with more water, a mature system, or a species-only setup. Read the pair page before you experiment.

  • 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.

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

Fish to avoid with Kribensis

Predation, aggression, or space rules on this profile. Treat these as poor default mixes.

  • Jack Dempsey reaches 25cm and is flagged predatory. Kribensis at 10cm is prey-sized for it.

  • Oscar reaches 35cm and is flagged predatory. Kribensis at 10cm is prey-sized for it. Oscar needs at least 300L, far above the 100L minimum for Kribensis. The tank that houses one stresses the other.

Tank size and groups

  • Published minimum for Kribensis: 100L. Group minimum 1 .
  • 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: 100L hub.
