The fish is stunning with its shimmering colors. It’s active and stays calm in a 5-gallon tank. I’ve kept it for three months and it’s still vibrant and healthy.
Paul Nash –
Beautiful colors and very peaceful. I noticed the blue and green flashes when it moves. Needs a stable temperature, but otherwise easy to care for.

A true eye-catcher. The turquoise and red spots are mesmerizing. I’ve seen it swim in circles and it looks like a tiny galaxy. Very happy with the purchase.
