Like most tetras, these fish prefer to be kept in schools of 5 or more in order to make them feel the most comfortable.

Received the Blue Diamond Neon Tetras in good condition. They were active and colorful when delivered. I kept them in a 10-gallon tank with other peaceful fish. They swim together in schools and look beautiful. Easy to care for and very lively.

The fish arrived healthy and the blue diamond on their forehead is very distinctive. I have kept them with guppies and they don’t seem to fight. They need a group of at least five, which I provided.

Great addition to my aquarium. The fish are active and show off their bright blue forehead markings. I followed the group size recommendation and they are now swimming together in a coordinated pattern.
