The Scarlet Badis are vibrant and active in a well-maintained tank. I noticed the males develop bright colors over time, which is a great sight. The tank needs dim lighting and stable water parameters, but once set up, they thrive in a species-only community.

I kept a small group of Scarlet Badis in a 10-liter tank. They are peaceful and don’t stress other small fish. The color change in males after a few weeks was impressive. I keep the lighting low and maintain pH between 7 and 7.5.

These fish are a delight to watch. The males become very colorful as they mature. I found the compatibility requirement strict, so I kept only other Badis species. Water parameters are easy to maintain with regular testing.
