Manage Water Quality & Temperature Diligently

It’s fundamental, but maintaining water quality and temperature will allow them to showcase their beautiful colors. Aim to mimic their natural habitat in Borneo by keeping the water slightly acidic and soft. Also, avoid mixing them with medium to large-sized fish. By providing a calm environment with minimal stress, you can enjoy their beauty to the fullest. Brigittae, perhaps due to its size, is more sensitive to water quality, so be careful when changing the water to avoid sudden shifts in temperature or quality.
