The Boesemani Rainbowfish are lively and colorful once they mature. I kept them in a 55-gallon tank with a group of six. They swim actively and the colors become more vivid after a few months. The tank needs enough space and a good filter, but it’s worth it for the visual appeal.

I bought one to start with, but after a few weeks I added more. They are social and enjoy swimming in open areas. The color development is slow at first but improves over time. Make sure your tank has enough horizontal space.

Great addition to a community tank. The fish are active and form a beautiful group. I followed the advice to keep them in a group and provide open swimming zones. They’ve been thriving for over six months now.
