The Gold Dust Geo is stunning with its golden body and blue iridescent scales. It’s active and peaceful, fits well in a community tank with other mid-sized fish. I’ve kept it for six months and it’s still vibrant and healthy.

Beautiful fish with a unique appearance. I noticed it digs in the sand regularly, so I made sure to use a fine sand substrate. It gets along well with my characins and doesn’t compete for space.

One of the most visually striking geophagus I’ve ever seen. The color pattern is impressive under aquarium lighting. It’s not aggressive and stays near the bottom, making it easy to observe.
