Sixline Wrasse

Pseudocheilinus hexataenia

A hardy, cheap, striking little wrasse with six neon-blue lines — a favourite that earns its keep by eating pest snails, flatworms, and bristleworms. The catch is temperament: it is an angelic juvenile that grows into a territorial bully, so it must be the last fish added to a community. It is also a strong jumper.
