The fish are vibrant and peaceful. I keep them in a small planted tank with java fern and moss. They don’t need much maintenance and stay active even in low-flow conditions.

Great addition to my nano aquarium. The blue color stands out well in the planted setup. Easy to care for and doesn’t stress other fish in the tank.
