I added a group of five Flame Tetras to my 20-liter tank. They swim together in a lively school and add vibrant color. The fish are active but calm, and I didn’t notice any fin-nipping. Good for beginners who want colorful movement.

The Flame Tetras are beautiful and active. I kept them with other peaceful species. They do best in groups, so I made sure to buy at least six. They adapt well to the water parameters and eat easily.

I’ve had these fish for three months now. They’re lively, colorful, and don’t stress the tank. I only keep them with similarly sized, non-aggressive fish. A great addition to a community tank.
