Added a Goyder River Rainbow to my 20-gallon planted tank. It’s vibrant and active, blending well with the live plants. The fish seems healthy and calm, not aggressive toward other community fish. Water parameters stayed stable after a few weeks.

The colors are striking, especially the red fins with black edges. It’s a bit larger than expected, so I made sure the tank had enough space and good filtration. It’s peaceful and doesn’t chase other fish.
