Why Choose Phoenix Rasboras?
Phoenix Rasboras are a great choice for aquarists who want a small, peaceful fish with bold natural color. Their red tones become especially attractive in stable planted aquariums with dark backgrounds, gentle lighting, and plenty of cover.
Because of their tiny size and calm personality, Phoenix Rasboras are best kept with other small, peaceful tankmates. A larger group helps them feel secure and encourages better color, confidence, and natural behavior.
Ideal Tank Setup
Phoenix Rasboras do best in mature, stable aquariums with live plants, moss, floating plants, and gentle filtration. Dark substrate, driftwood, botanicals, and shaded areas can help create a comfortable environment while enhancing their red coloration.
Low to moderate flow is preferred. Avoid housing them with large, aggressive, or overly active fish, as Phoenix Rasboras are small and can be easily outcompeted or stressed.
