Celebes Rainbowfish should always be kept in groups, as they are highly social and feel more secure in schools. A group of 6 or more is recommended to bring out their best coloration and natural behavior.

They thrive in well-planted aquariums with open swimming space near the top. Gentle to moderate water flow is ideal, and a secure lid is recommended as they can be active jumpers.

Feed a varied diet including high-quality flakes or micro pellets, along with frozen or live foods such as baby brine shrimp, daphnia, and bloodworms. A balanced diet helps enhance their color and overall health.
