Carol Watson –
I bought a group of five Lambchop Rasbora and they’ve been thriving in my 10-gallon tank. They’re very peaceful and the lambchop pattern is quite striking. Easy to care for and they don’t stress other fish. Great addition to my setup.
Amelia Davies –
The fish arrived healthy and were already active in the tank. I kept them in a group of six and they seem to get along well. They don’t need much maintenance and stay calm even with other species.

Perfect for a small tank. The fish grow slowly and stay small, which is ideal for a nano aquarium. I’ve had them for three months and they’re still vibrant and active.
