The fish arrived healthy and active. I kept them in a 10-gallon tank with other peaceful species. They swim together in a school and are very colorful. Easy to care for and don’t stress other fish.
Carol Vaughan –
Great addition to my aquarium. The red color stands out well. I kept six as recommended and they seem to be getting along well with my tetras and corydoras.
Frank Walker –
They’ve been in the tank for three months and are still vibrant. The water parameters are stable, and they eat the small flakes and algae wafers I offer daily.
