Sam Jones –
I added five Reed Tetras to my 60-liter tank with live plants. They swim together in a natural school and look very peaceful. The color is subtle and fits well with my biotope setup. Easy to feed and they don’t stress other fish.
Anne Hodges –
The fish are active and beautiful in a group. I kept them with other small tetras and they coexist well. Water parameters stayed stable, and they seem healthy after two months.

Perfect for a natural look. I didn’t have to adjust much in my tank setup. They stay in the mid-level and swim together in a coordinated way. Very satisfied with the purchase.
