The fish arrived quickly and were healthy. I kept them in a 20-gallon tank with other peaceful community fish. The males show off their fins beautifully when the school is active. Easy to care for and very active in the tank.

I bought a small school and they seem to get along well. The females are less flashy but still attractive. The tank looks vibrant with their colors and movement. Good for beginners looking for colorful, peaceful fish.

Perfect addition to my community tank. The males are stunning with their flowing fins. I have six fish now and they swim together in a coordinated way. Very peaceful and don’t stress other fish.
