  • Juveniles:Juveniles primarily feed on small invertebrates, such as zooplankton and small crustaceans.
  • Adults:Adult Ikan Gelama Kuning exhibit a broader diet, including small fish, larger invertebrates, and occasionally even smaller members of their own species.

Reproduction and Life Cycle

Ikan Gelama Kuning exhibits a complex reproductive cycle influenced by various environmental factors. The species displays a distinct mating behavior, specific spawning grounds, and a unique larval development pattern.

Mating Behavior

During the breeding season, male Ikan Gelama Kuning engage in elaborate courtship displays to attract females. They establish territories and aggressively defend them against rival males. The courtship ritual involves swimming in circles around the female, displaying their vibrant coloration, and performing synchronized body movements.

Spawning Grounds

Ikan Gelama Kuning migrate to specific spawning grounds during the breeding season. These grounds are typically located in shallow, well-oxygenated waters with abundant vegetation. The females select suitable nesting sites, which are usually depressions in the substrate or among aquatic plants.

Larval Development

After fertilization, the eggs hatch into larvae that undergo a series of developmental stages. The larvae initially feed on plankton and gradually transition to a predatory diet as they grow. They undergo several molts as they develop, shedding their exoskeletons to accommodate their increasing size.
