Males have a vibrant pink or purple body with a yellow-banded neck, and a green or blue head, while females and juveniles have horizontal black and yellow stripes with a lower pink stipe above the belly. They reach a maximum size of 8 inches and should be monitored around crustaceans, as they tend to feed on shrimp and crab.
