Celebes Rainbowfish
The Celebes rainbowfish comes from the island of Sulawesi, which used to be known as Celebes, hence the common name of this fish. In the wild, they are found in clear, swift streams and estuaries.
Being a fairly skittish shoaling fish, the Celebes rainbowfish does best in a group of 6 or more. They can be kept in mildly brackish conditions and are compatible with other peaceful, small species such as some gobies and halfbeaks.

I kept a group of six Celebes rainbowfish in a 55-gallon tank with some halfbeaks. They’re active and colorful, though they do need a quiet environment. The water parameters stayed stable with a bit of brackish mix. Great for a community tank with small, peaceful fish.

The fish arrived healthy and are now swimming in a group. I noticed they hide when there’s movement, so I made sure the tank has open space and no sudden changes. They seem happy and active in the morning light.

After adding them to a tank with gobies, the fish adapted well. The water was slightly brackish, and they stayed active without aggression. I recommend keeping them in a group of at least six for best results.
