A popular choice for the saltwater aquarium, the Basslet, is hardy, fairly well-behaved, and excellent for saltwater beginners despite its slightly territorial nature. Basslets are brightly colored fish often found in bright reds, oranges, yellows and purples, sometimes all at once. Their small size makes them ideal for smaller tanks; however they are quite territorial and still need some space. Their sleek, aerodynamic design and half-moon shaped tail make them ideal for sudden bursts of speed necessary when feeding or for defense; however, the Basslet is also a slow swimmer that will school with its own kind in the wild. In the ocean, this species will live in colonies called harems. These colonies will hover over a chosen coral head feeding, a behavior they will readily exhibit in your home aquarium. An interesting thing to note about the Basslet is that it is what is known as a “sequential hermaphrodite”. All fish are born female and develop into males as they mature, with one “supermale” leading the colony until its death.
