The species is conspicuous for the very tall, sail-shaped dorsal fin of the males, which they raise during courtship. It inhabits brackish and fresh coastal waters, mangroves and coastal pools. As an omnivore it grazes algae, detritus and small invertebrates such as worms, crustaceans and insects. The females bear live young. Owing to habitat pressure the species is considered vulnerable. It is harmless to humans.
