What fish can live with Apistogramma Borellii?

Use the "Often compatible" lists as a shortlist, not a stocking plan. Always run the pair tool and check the footprint of your actual tank first. Verify behaviour for Apistogramma Borellii against your own reading before you buy.

What tank mates should you avoid with Apistogramma Borellii?

Avoid Tiger Barb, Oscar, Jack Dempsey, Common Pleco based on size, temperament, or predation risk on file.

What size tank do Apistogramma Borellii need for a community?

80L is the planning floor for adult swimming space and bioload headroom. Long-term, a 100L+ tank lets adults use the full footprint without crowding the next species. Footprint, meaning length and front-to-back depth, matters as much as raw volume for active or territorial species.

Corydoras Catfish Pair check
The Apistogramma Borellii 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.
Harlequin Rasbora Pair check

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.

Dwarf Gourami Open pair check
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.

Fish to avoid with Apistogramma Borellii

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

Tiger Barb See why (pair)
Tiger Barb conflicts with Apistogramma Borellii on temperament, predation, or footprint. The juvenile size in a shop tank is not the figure that matters here.
Oscar See why (pair)
Oscar reaches 35cm and is flagged predatory. Apistogramma Borellii at 6cm is prey-sized for it. Oscar needs at least 300L, far above the 80L minimum for Apistogramma Borellii. The tank that houses one stresses the other.
Jack Dempsey See why (pair)
Jack Dempsey reaches 25cm and is flagged predatory. Apistogramma Borellii at 6cm is prey-sized for it. Jack Dempsey needs at least 200L, far above the 80L minimum for Apistogramma Borellii. The tank that houses one stresses the other.
Common Pleco See why (pair)
Common Pleco needs at least 600L, far above the 80L minimum for Apistogramma Borellii. The tank that houses one stresses the other.

Tank size and groups

Published minimum for Apistogramma Borellii: 80L — 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: 80L 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.
