The fish are very active and colorful. I kept six of them in a 120-liter tank with good filtration. They swim together in a tight group and the red line pattern is striking. Only issue is they need a lot of open space and a strong filter.

Beautiful fish with vibrant red and black markings. I’ve had them for three months and they’re healthy and active. Make sure your tank is large enough and has good oxygen flow.

Great addition to my community tank. The shoaling behavior is natural and entertaining. I noticed they stay calm when kept with non-aggressive species like tetras and guppies.
