The Scarlet Gem Badis is a fascinating addition to my tank. The males are striking during breeding season, showing clear color changes and interesting behaviors. I keep them in a heavily planted tank with sand substrate and they seem calm and well-adjusted.

I was initially skeptical about a shy fish, but the Scarlet Gem Badis has adapted well. The coloration is vivid, especially in males during spawning. I’ve noticed the males interacting in a natural way, which is both beautiful and engaging.

This species adds a unique touch to my community tank. The tank looks more dynamic with the fish moving subtly through the plants. I appreciate how they don’t dominate the space and stay peaceful with other small fish.
