The orange colouration is striking and the fish are very active. I kept them in a 20-gallon planted tank with other peaceful species. They adapt quickly and stay healthy with regular water changes.
Emma Miller –
Great for small aquariums. The fish are social and enjoy swimming together. I noticed their colours look best under bright lighting, but they are still lively even in moderate light.

I bought this for my daughter’s school project. The fish are easy to care for and look very vibrant. They have been in the tank for three months and show no signs of stress.
