Grass Puffer

About

The grass puffer (Takifugu niphobles) is a compact, personable saltwater puffer from the coastal waters of the Northwest Pacific, ranging from Japan and southern Korea down through Vietnam. Like other members of its family, it has the classic puffer body plan, a rounded, slightly squared-off profile capable of inflating when stressed, but what really sets this fish apart is its reproductive behavior. At high tide, large groups of adults will actually haul themselves ashore onto beaches to spawn, leaving their eggs partially buried in the sand and rubble to develop. It is a remarkable strategy you just don't see in most aquarium fish. In the home aquarium, the grass puffer is considered approachable even for newer marine fishkeepers, which is not something you can say about many puffers. That said, the typical puffer caveats still apply. These are intelligent, curious, and dentally well-equipped fish that will investigate (and potentially nibble) tankmates and decorations. A carnivorous diet with hard-shelled foods helps keep their ever-growing teeth in check. Given a suitable setup with compatible tankmates and appropriate feeding, this is a characterful little fish that rewards attentive keeping.
