My Lemon Tetras have been in the tank for three months and now show vibrant yellow bodies. I kept them in a group of six and the colors are much more vivid than when they first arrived. They are very active and peaceful, and don’t bother other fish.

The fish arrived healthy and seemed a bit pale at first. After a few weeks in a well-maintained tank with a group of six, they started to turn yellow. I feed them a mix of flakes and frozen foods daily. They are easy to care for and look great in a community tank.

I bought these for my new 20-gallon tank. The fish are calm and don’t chase each other. After two months, they’ve developed nice yellow coloring. I’m happy with the quality and the fact they’re captive bred.
