I’ve had my licorice gourami for three months now. It’s very active and shows off its iridescent bands beautifully. I keep it in a 10-gallon tank with java fern and moss. The water needs to be soft and acidic, which I’ve maintained with regular water changes. It’s peaceful and doesn’t stress other fish.

The fish arrived healthy and looks vibrant. I noticed the males have a unique shimmer when the light hits them. I’ve been adjusting the pH to 6.2 and keeping the temperature stable. It’s a small but eye-catching addition to my planted tank.
