The Threadfin Rainbowfish are beautiful and active in the tank. They swim gracefully and the males’ long fins are very striking. Easy to care for and get along well with other small fish. A great addition to a community aquarium.

I’ve had these fish for three months and they’re still healthy and active. The colors are vibrant and they seem to enjoy the water flow. A bit shy at first, but they settle in quickly.

These fish are a highlight in my tank. The thread-like fins on the males are truly unique and add a lot of visual interest. They don’t stress other fish and are easy to maintain.
