About

The Dwarf Pea Puffer is the world's smallest pufferfish, a true freshwater species endemic to the rivers, lakes and floodplains of Kerala in southwest India. Despite topping out near 3.5 cm it has an outsized personality: it hovers and hunts like a tiny hawk, tracking prey with independently swivelling eyes. Males are territorial and the species needs a heavily planted, sight-broken tank plus a steady supply of live or frozen invertebrates, so it rewards experienced keepers rather than beginners.

Care

Species-only, heavily planted tank with a female-skewed group; feed live/frozen snails and worms — it ignores dry food.

Diet

Obligate micro-carnivore; relishes small ramshorn/bladder snails, bloodworm, blackworm and brine shrimp. Snails help wear down its ever-growing beak.
