Maintain gentle water flow and consider dim lighting to reduce stress, which can be beneficial for their vibrant coloration.

Mosquito Rasbora Tank Mates
Ideal companions include other small, peaceful fish that share similar swimming zones and temperaments, such as micro-rasboras or small tetras. Avoid larger or more boisterous species that could intimidate them. Within their own species, keeping groups of at least six fosters natural behavior, as they are less likely to display stress or skittishness in larger shoals.
