I bought a group of Green Neon Tetras for my 50-liter tank. They are very active and their colors are stunning. They don’t stress other fish and have adapted well to the tank conditions. I feed them a mix of flake and frozen food every day.

The fish arrived healthy and stayed active in my aquarium. I kept them in a group of six and they swim together in a school. They seem to enjoy the live food I offer.

Great addition to my community tank. They are peaceful and don’t chase other fish. Their green color stands out well in the water. I’ve had them for three months and they’re still vibrant.
