I bought six Neon Tetras for my 10-gallon tank. They are very active and create a beautiful, colorful display. The blue and red stripes stand out well in the water. I’ve kept them for three months and they’re still healthy and lively.

The fish arrived quickly and looked healthy. I kept them in a group of seven and the color pattern is stunning. They swim together in a coordinated way, which makes the tank look more dynamic.
