The Rosy Barbs are lively and active, forming a nice school in the tank. They adapt well to my 60-liter aquarium with proper water parameters. Easy to care for and add a lot of visual appeal.

I bought a small group and they’ve been peaceful and active. They seem to thrive in a well-maintained tank with regular water changes and a balanced diet.

The fish are colorful and active, especially when the tank has plants and some hiding spots. I’ve kept them for three months and they’re still healthy and showing good schooling behaviour.
