Antennata Lionfish
The Antennata or Spotfin Lionfish is the elegant middleweight of the group — quill-like dorsal spines, spotted pectoral fans, and a fraction of the bulk a volitans grows into. It hunts from cover after dark and swallows prey whole, so ornamental shrimp and any fish it can fit in its mouth are food rather than tankmates. The dorsal, pelvic and anal spines are venomous and sting like a bee, only harder, which makes routine maintenance a deliberate act. The honest catch is the first few weeks: new arrivals frequently refuse frozen food and need live shrimp to start eating, and weaning them over can take months.
