The fish arrived quickly and were very active in the tank. Their bright blue color stands out in a small planted setup. Easy to care for and very peaceful. I’ve kept them for three months and they’re still doing well.

Great color and hardy. Perfect for a nano tank. The fish adapted quickly to my planted aquarium with minimal water changes. I appreciate the in-house breeding quality.

Arrived on time via UPS. The fish are vibrant and stay calm in the tank. A bit shy at first, but settled in after a week. Would recommend for small, low-flow setups.
