This species is known for its striking appearance, featuring a magnificent yellow and maze-like pattern on its back.
For optimal tank setup, we recommend a sandy substrate with smooth rocks and driftwood for decoration. Provide ample open swimming space. Plants can be included, but be aware that the fish may bite leaves if it spots food on them.

The Mbu puffer is a stunning fish with a unique yellow maze pattern. It’s quite large and very active. I kept it alone as recommended. It’s aggressive, so I didn’t add any other fish. It’s a bold choice for a freshwater tank.

Beautiful fish with a striking appearance. I noticed it bit a few leaves when food was on them. The tank needs open space and a sandy bottom. It’s not for beginners due to its aggression.
