Clownfish
Maroon Clownfish
Amphiprion biaculeatus
The largest and most pugnacious of the clownfishes — a deep maroon fish with white (or gold) bars and cheek spines that give it its old genus name. A female can reach a genuine 15 cm and will dominate a tank, so it is kept singly or as a single bonded pair (a big female with a small male) and added after more peaceful fish. Hardy and reef-safe, but its temperament, not its care, is what makes it an intermediate fish.
Keep just one per tank — two will fight.
