The fish are vibrant and easy to care for. I added them to my community tank with other peaceful fish and they blend well with the green plants. The males are active but don’t fight, which is great for a beginner setup.

They look stunning in a dark gravel tank. The red color is very noticeable and the fish are active without being aggressive. I’ve had them for three months and they’re still healthy and lively.

Perfect for a small aquarium. The fish are colorful and calm. I noticed the males have subtle yellow and black markings that stand out in the light. They eat a variety of foods and stay healthy.
