Half Moon Damsel

The bold half-and-half color split gives this damsel its name and makes it easy to pick out even from across the store — typical damsel toughness underneath, tolerant of the water swings that would stress out more delicate reef fish, with a territorial streak that shows up once it's staked a claim on the rockwork.
