Boesemani Rainbowfish tank mates
One of the hobby's most spectacular mid-water fish. Full halved colouration requires a mature school of six or more males in a planted tank of 200L or more.
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 Boesemani Rainbowfish 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 Boesemani Rainbowfish stays in the middle, so the two will not crowd the same water column.
The Boesemani Rainbowfish profile lists Platy as both safe and a recommended pairing. Platy is a peaceful beginner-care species with a 60L minimum. Run the pair checker for your specific tank before stocking.
The Boesemani Rainbowfish profile lists Siamese Algae Eater as both safe and a recommended pairing. Siamese Algae Eater is a peaceful beginner-care species with a 100L minimum. Run the pair checker for your specific tank before stocking.
The Boesemani Rainbowfish 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.

Tank size and groups
- Published minimum for Boesemani Rainbowfish: 150L — group minimum 6 (schooling).
- 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: 160L 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.
