Clownfish
Clownfish are arguably the most recognizable saltwater fish in and outside the hobby. Their relationship with sea anemones is fascinating to watch. Without their hosts, most anemone fishes would die in the wild as a result of predation by large morays, trumpetfishes, scorpionfishes, large hawkfishes, snappers, and groupers. This does not always hold true in captivity as they do not need hosts to survive or thrive. They even spawn regularly without the presence of an anenome. They do however host other objects in the aquarium, from other types of anenomes, plants, to LPS, soft corals, macro algae, and even powerheads.[ref]Ref[/ref] Captive-bred clownfish have become widely available now and they are generally more disease-resistant and hardier.
