I’ve had my Emerald Rainbow for three months now. It’s very active and colors are vibrant. The tank is planted and it seems to do well with the plants. Water temperature stays below 80°F, and it’s been very calm and healthy.

The fish looks stunning with its deep green body. It’s not aggressive and fits well in a community tank with other peaceful species. I noticed it’s more active during the morning hours.
