Quick answer: Boesemani is a variety of rainbowfish. Everything on this page is rainbowfish-level guidance — we do not invent variety-specific numbers.

The care below is rainbowfish-level guidance from our species hub, sourced to Merck Veterinary Manual — Aquarium and Pond Fish and RSPCA — Fish care. It applies to Boesemani exactly as it applies to every other rainbowfish variety. We do not publish variety-specific temperament, lifespan or weight numbers that we cannot source.

How long do rainbowfish live

Rainbowfish live 5–8 years with stable, clean water. They are robust but color and health decline fast in poor conditions; ammonia and nitrate spikes and bullying from wrong tank mates are the usual problems. A planted tank, a school of 6+, and regular water changes keep them vivid and long-lived.

Tank and the color trigger

Keep 6–10 in a 20–30 gal (75–115 L) tank with plants and open swim space. They prefer harder, alkaline to neutral water (pH 7.0–8.0) and warmer temps (74–80°F / 23–27°C) than soft-water species. Good diet and a school bring out the iridescence; isolation and stress keep them grey.
