The body and head are bright blue, darkening to almost black on the back just below dorsal fin. The deeply forked tail, dorsal fin and anal fin are edged in black. The blue chromis grows to a length of 5 inches (13 cm). The blue chromis is abundant throughout the Caribbean, including in the Cayman Islands. It swims in schools mid-water above coral reefs, feeding on zooplankton. Occasionally, schools will be mixed with the brown chromis and creole wrasse.
