The fish is very active and colorful. The red fins stand out well in the tank. I made sure to provide a spacious tank with plenty of hiding spots. They seem healthy and enjoy the food I offer.

Beautiful fish with a striking appearance. The black stripe on the tail is very noticeable. I keep them in a 20-gallon tank and they are happy and active. Feeding them requires attention, but it’s worth it.

Great addition to my community tank. The fish swim gracefully and look vibrant. I’ve noticed they eat quickly, so I feed them in small portions twice a day.
