Endler's Livebearer tank mates
A 3.5 cm nano livebearer that breeds as quickly as guppies. Males display constantly. Fry survival in a planted tank produces rapid population growth.
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 Endler's Livebearer profile lists Cherry Barb as both safe and a recommended pairing. Cherry Barb schools in groups of 6 or more, so plan room for the whole group rather than one fish.
The Endler's Livebearer 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. Corydoras Catfish swims in the bottom zone while Endler's Livebearer stays in the top, so the two will not crowd the same water column.
The Endler's Livebearer profile lists Honey Gourami as both safe and a recommended pairing. Honey Gourami is a peaceful beginner-care species with a 40L minimum. Run the pair checker for your specific tank before stocking.
The Endler's Livebearer profile lists Neon Tetra as both safe and a recommended pairing. Neon Tetra schools in groups of 6 or more, so plan room for the whole group rather than one fish. Water parameters barely overlap between the two, so check the temperature and pH ranges on both profiles before stocking.

Fish to avoid with Endler's Livebearer
From the unsafe list — predation, aggression, or space rules on this profile.
Oscar reaches 35cm and is flagged predatory. Endler's Livebearer at 3.5cm is prey-sized for it. Oscar needs at least 300L, far above the 40L minimum for Endler's Livebearer. The tank that houses one stresses the other. Oscar is rated aggressive and Endler's Livebearer is rated peaceful. No community-style planning carries that gap.
Betta conflicts with Endler's Livebearer on temperament, predation, or footprint. The juvenile size in a shop tank is not the figure that matters here.
Tiger Barb conflicts with Endler's Livebearer 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 Endler's Livebearer: 40L — group minimum 4 .
- 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: 40L hub.

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