How the Boesemani Rainbowfish and Dwarf Neon Rainbowfish compare on care, size, water and temperament, and which fish suits your tank.
By Mike ElmiraUpdated
TL;DR, Boesemani Rainbowfish vs Dwarf Neon Rainbowfish
The Boesemani Rainbowfish and the Dwarf Neon Rainbowfish are close cousins, both in the Melanotaenia group, so at a glance they ask for a lot of the same things. Both are happy somewhere around 24 to 28 °C and pH 7 to 7.5, so a single tank can suit either one. Neither is harder than the other to keep, so the choice comes down to look and stocking rather than skill. If tank space is tight, the Dwarf Neon Rainbowfish needs less room to feel settled; give the Boesemani Rainbowfish the nod when you have the litres to spare.

What to plan for
- Boesemani Rainbowfish schools, stock at least 6You've planned for 1 boesemani rainbowfish. Boesemani Rainbowfish need a group of at least 6 to feel safe and shoal naturally, below that they're stressed and lose colour. Dial up the count, or remove the species.
- Dwarf Neon Rainbowfish schools, stock at least 6You've planned for 1 dwarf neon rainbowfish. Dwarf Neon Rainbowfish need a group of at least 6 to feel safe and shoal naturally, below that they're stressed and lose colour. Dial up the count, or remove the species.
- No bottom teamNo bottom-dwelling fish or shrimp. A small group of corydoras or a shrimp colony picks up leftover food and keeps detritus in check.
