Clownfish Care: Facts, Types, Feeding, Breeding, and Lifespan
General information
Clownfish, or Amphiprion, are a genus of marine fish from the family Pomacentridae. Like most saltwater fish, clownfish have a bright, memorable appearance. These fish have a rich orange or red color and characteristic white stripes on the body.
Amphiprion’s exciting feature is its symbiosis (mutually beneficial cohabitation of two organisms) with various types of anemones. These coelenterates have stinging cell tentacles that can cause severe burns or even kill small animals. However, clownfish use the tentacles of sea anemones as a natural refuge. You may ask – why does the venom of anemones not work on these saltwater fish?
And the answer is pretty simple. In the process of evolution, Amphiprion has adapted to secrete special protective mucus, which makes the fish insensitive to the venom of anemones. Before settling in their new “home,” clownfish carefully allow being stung, and the fish’s body produces the necessary mucus in response to this irritation.
Thus, Amphiprion is reliably protected from attacks by other species. At the first sign of danger, these saltwater fish hide among the tentacles of anemones, and it will be a challenging time for anyone who tries to follow them. For this reason, clownfish rarely swim far from their “home.”
ThThese fish provide significant benefits to coelenterates, too, clearing their tentacles of food debris and ventilating the water between them, as well as luring other fish with their bright color. [3]
Amphiprion Ocellaris are highly territorial. If there are not enough anemones in the surroundings, there will be a bloody struggle between the fish for “a place in the sun.” Researchers believe that the bright color of fish appeared precisely to warn their relatives that the place is occupied.
The next feature of the clownfish is that all fry are born as males. Only under suitable conditions, for example, when the leading female in the school dies, one of the males becomes a female. In nature, these saltwater fish live in schools headed by a pair of the most significant individuals, and the other group members stop growing and are always smaller than the main couple.
