The fish are active and show beautiful blue-eye displays. They thrive in a well-planted tank with moderate flow. I kept them in a group of five and they seem to get along well. Easy to care for once the water parameters are stable.

They are colorful and peaceful. I noticed their finnage is delicate, so I made sure to avoid strong currents. They do need a group to stay happy, and I’ve seen them interact nicely with other small fish.

Great addition to a planted tank. The fish are active but not aggressive. I’ve kept them for three months now and they’ve adapted well to the tank conditions. The blue-eye behavior is quite charming.
