Damsel
Yellowtail Damsel
Chrysiptera parasema
A hardy little damsel with a deep-blue body and a bright lemon tail — widely considered the best-tempered of the common damsels and a good first saltwater fish. It largely ignores other species and is completely reef-safe, though it will squabble with its own kind, so it is safest kept singly or as an odd-numbered small group in a larger tank. Colourful, cheap, and forgiving, with only mild damsel territoriality to manage.
Keep just one per tank — two will fight.
