The OB Red Zebra is a striking fish with unique black spot patterns. It’s aggressive, so I made sure to keep it with other Mbuna fish. The water parameters are stable and the fish stays active in a 20-gallon tank with proper filtration.

I bought this for my community tank. The fish is very active and the spots are quite distinct. I had to be careful with tank mates, but it’s a great addition to a Malawi-style setup.

Captive bred and healthy from the start. The fish shows natural color variation and is very responsive to feeding. I keep it in a 30-gallon tank with hard water and stable pH.
