Soft substrates are preferable, allowing for foraging, while moderate lighting can enhance their vibrant colors. A gentle water flow complements their mid-water swimming habits.

Ideal companions include similarly sized, peaceful species that occupy various tank zones, such as small rasboras or other tetras. Avoid aggressive or overly territorial fish that might stress them; larger cichlids could pose a risk. Maintaining a minimum group size of six is crucial to prevent stress and promote natural shoaling behavior.
