Monogamy

Monogamy: A mating system where partners live and exclusively mate with only each other.  These pair bonds can be transitory, just for a single breeding season, extend for several years or even a lifetime.  Fish that form strong pair bonds include: American freshwater catfish, some cichlids, and many butterflyfish.  The Four-Eyed Butterflyfish (Chaetodon capistratus) is.. read more →
