The Kyathit Danios are very active and colorful. I kept them in a 10-gallon tank with other danios and they swim together beautifully. The orange fins stand out well, especially with a dark gravel substrate. They adapt quickly to the tank and seem healthy after a few weeks.

These fish are lively and easy to care for. I noticed their colors brighten up after a few weeks of consistent feeding. The striped and spotted varieties look different, which adds variety to the tank. I would recommend them to other aquarists looking for vibrant, active schooling fish.

Great addition to my community tank. The fish are peaceful and form tight schools. The orange fins are very noticeable and add a nice visual contrast. I’ve kept them for over two months and they remain healthy and active.
