Humpback Grouper

About

The humpback grouper (Cromileptes altivelis) is one of the most recognizable fish in the saltwater hobby, wearing a pale body covered in a dense scatter of dark spots that runs from nose to tail. Juveniles especially look almost unreal. The profile is equally distinctive: a steeply concave forehead and a hunched back give the fish its common name and make it impossible to confuse with anything else. In the wild it ranges across a broad sweep of the Western Pacific and Eastern Indian Ocean, turning up on lagoon and seaward reefs, silty or degraded reef areas, and even tide pools. It grows slowly, which is actually part of why juveniles show up so often in the aquarium trade. Small specimens are commonly collected and are genuinely manageable in a suitably large system. Behavior is where this fish really wins people over: it is active, curious, and quickly learns to associate its keeper with food, often pressing against the front glass in anticipation. That personality comes with a catch, though. It is territorial and will harass tankmates, particularly newcomers or others of its own kind. Diet is straightforward carnivore fare: meaty foods and prepared diets. Despite the aggressive label, experienced reef keepers often describe it as a rewarding and personable long-term resident.
