Beautiful fish with a striking color pattern. The rainbow splashes and purple tail stand out. It’s active but not aggressive, and it’s a great addition to a 10-gallon tank with compatible fish.

I’ve had this male guppy for three months and it’s still very active and healthy. The color changes slightly in different lighting, which is a nice touch. It pairs well with other non-aggressive fish.
