Indochinese Puffer

Pao cochinchinensis is broadly distributed across the major river systems of Indochina and is one of the more commonly imported medium Pao species in the specialist trade. Its olive-green body is adorned with irregular yellow-brown spots and blotches. It is a powerful feeder capable of consuming large snails whole and requires correspondingly sturdy filtration to manage the resulting waste.

Water: 24–28°C, pH 6.5–7.5, moderately hard; high filtration capacity needed due to messy feeding habits. Tank: Minimum 120 L; robust decor — driftwood and rocks — as it may rearrange lightweight ornaments. Feeding: Large snails, cockles, clams, mussel on the half-shell, and earthworms. Behaviour: Bold, highly territorial, and aggressive toward any fish; may also attack handler's hands. Compatibility: Species-only; individual housing in a dedicated aquarium is mandatory.
