Spanish Hogfish
A Caribbean classic, the Spanish Hogfish wears a deep blue-to-violet upper body over a rich golden-yellow underside, and as a juvenile it earns its keep picking parasites off larger fish. It is hardy and long-lived, but it does not stay small — FishBase lists it to 40 cm — and with size comes a serious predatory streak. Adults crunch through brittle stars, urchins, crabs, snails and shrimp, making it strictly a fish-only or big-tank resident. Give it space, a heavy meaty diet and no prized inverts.
