DIET IN THE WILD: Sexy shrimp are carnivorous feeding on matter trapped in a host anemone’s mucus, including plankton. Their diet may also include other small crustaceans, such as brine shrimp and krill. When resources are scarce, shrimp may resort to feeding on the tentacles of their hosts.

REPRODUCTION: Mating is polygynandrous (promiscuous).  T. amboinensis are sexually dimorphic. Males are typically smaller than females and have white spots on their pleopods. Sexy shrimp are protandric hermaphrodites; there are no primary females but that all individuals are born male and transition into females later in life.
