The fish are beautiful with a striking red glow that stands out in the tank. Easy to care for and very peaceful. I’ve had them for six months and they’re still active and healthy.
Olivia Dickens –
The glowing effect is impressive, especially at night. They don’t stress other fish and adapt well to the tank environment. Only need to feed them twice a day with a mix of flakes and frozen food.

I bought this as a centerpiece for my 10-gallon tank. The color and movement are captivating. Water temperature stays stable and they thrive in the 75°F range.
