The fish are incredibly vibrant with bright blue and orange colors. I kept one male and two females in a 10-gallon tank with peat substrate. They were active and displayed frequently. The lifespan is short, but the visual impact is unforgettable.

Great for a short-term display. The males are very active and show off to females. I feed them frozen bloodworm daily and they accept it well. Not suitable for a community tank due to aggression.

The coloration is stunning. I’ve had one male and two females for about 10 months and they’ve produced a few spawns. The tank needs a sandy or peat base, which I’ve provided. A unique and eye-catching addition to any freshwater setup.
