If a new Fula gets into an aquarium where there is already a group, the male leader, supported by the rest, will constantly attack it to death.<\/p>\n<figure id=\"attachment_1314\" class=\"wp-caption alignnone\"><img loading=\"lazy\" class=\"size-full wp-image-1314\" src=\"http:\/\/blog.fuertecharter.com\/wp-content\/uploads\/2015\/07\/www.colchonero.com_.jpg\" alt=\"Excursiones Fuertecharter | The Canary Damsel in Fuerteventura\" width=\"400\" height=\"267\" srcset=\"https:\/\/blog.fuertecharter.com\/wp-content\/uploads\/2015\/07\/www.colchonero.com_.jpg 400w, https:\/\/blog.fuertecharter.com\/wp-content\/uploads\/2015\/07\/www.colchonero.com_-300x200.jpg 300w\" sizes=\"(max-width: 400px) 100vw, 400px\" \/><figcaption class=\"wp-caption-text\">\u00a9www.colchonero.com<\/figcaption><\/figure>\n<p>They quickly take control of the space they inhabit, confronting fishes even much bigger than themselves.<\/p>\n<p><strong>Behaviour<\/strong><br \/>\nThey are diurnal. They tend to move in fairly dense banks, dominated by the largest male. Males can also be found on their own or living with their breeding females.<br \/>\nA male can mate with several breeding females, spawning in summer (what is known as Spawn), in crevices or in nests composed of a group of several rocks, which the male will watch closely during the 3-day incubation period, even ready to kill another male approaching the egg laying area, less than 1 meter radio.<br \/>\nIn the fighting, males increase their breathing rate, producing very distinctive sounds in combat; as they belong to teleost fish, which are those with specialized organs to emit sounds.<br \/>\n<strong><br \/>\nMorphology<br \/>\n<\/strong>Robust and compact body on their sides, covered with large visible scales, with short and fairly rigid fins. Their eyes and mouth are small and they have a small bulge on their head. They have sharp teeth in both jaws.<br \/>\nThe colouring which young specimens feature, up to 3 years old, is very striking. They are almost black, with electric blue stripes that sometimes create whimsical patterns. From the age of 3 their color changes from black to grayish brown, excep in their head and the dorsal and caudal fins, which take a very dark blue colour. In the adult specimens the electric blue stripes condense on the edges of their fins and head.<\/p>\n<figure id=\"attachment_1315\" class=\"wp-caption alignnone\"><img loading=\"lazy\" class=\"size-full wp-image-1315\" src=\"http:\/\/blog.fuertecharter.com\/wp-content\/uploads\/2015\/07\/www.elmar_.es_.jpg\" alt=\"Excursiones Fuertecharter | The Canary Damsel in Fuerteventura\" width=\"780\" height=\"585\" srcset=\"https:\/\/blog.fuertecharter.com\/wp-content\/uploads\/2015\/07\/www.elmar_.es_.jpg 780w, https:\/\/blog.fuertecharter.com\/wp-content\/uploads\/2015\/07\/www.elmar_.es_-300x225.jpg 300w\" sizes=\"(max-width: 780px) 100vw, 780px\" \/><figcaption class=\"wp-caption-text\">\u00a9www.elmar.es<\/figcaption><\/figure>\n<p>They are usually 8 to10 cm long and males, slightly larger than females, can reach up to 15cm.<br \/>\nAn oddity of this species is that there are specimens that are pale orange in the back of their body to the tail, a phenomenon whose cause is scientifically unknown.<\/p>\n<p><strong>Feeding<\/strong><br \/>\nThey feed mainly on small invertebrates found among the algae. The young fish are extremely sensitive to food, only eating marine plankton, so those which are bred in captivity tend not to survive unless they are given food of this type.<\/p>\n<figure id=\"attachment_1313\" class=\"wp-caption alignnone\"><img loading=\"lazy\" class=\"size-full wp-image-1313\" src=\"http:\/\/blog.fuertecharter.com\/wp-content\/uploads\/2015\/07\/www.arona_.travel.jpg\" alt=\"Excursiones Fuertecharter | Fula Negra en Fuerteventura\" width=\"1024\" height=\"768\" srcset=\"https:\/\/blog.fuertecharter.com\/wp-content\/uploads\/2015\/07\/www.arona_.travel.jpg 1024w, https:\/\/blog.fuertecharter.com\/wp-content\/uploads\/2015\/07\/www.arona_.travel-300x225.jpg 300w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-caption-text\">\u00a9www.arona.travel<\/figcaption><\/figure>\n<p><strong><em>FuerteCharter<\/em><\/strong><em><strong> Team<\/strong><\/em><\/p>\n<\/div>\n<p><\/p>","protected":false},"excerpt":{"rendered":"<p>Abudefduf luridus, Fula negra, Casta\u00f1eta or casta\u00f1uela, as it is known in some parts of the Canary Islands, is a very colorful fish, belonging to the damsels, a percomorphi species of the Pomacentridae family.
