The Cardinal Tetras arrived healthy and vibrant. They’ve been in my 10-gallon tank for two months and are very active. The colors are bright and they swim in schools, adding a lot of visual interest. Easy to care for and compatible with my other fish.
Warren Blake –
Great addition to my community tank. The fish are lively and stay calm around other species. I keep the water temperature stable and pH slightly below 7.0, which seems to suit them well.

I bought a small group and they’ve formed a tight school. They look stunning in the evening light. The tank is now much more dynamic and colorful. No issues with aggression or health so far.
