Синьоивичатият зеленоглав ( Labriodes dimidiatus ) е един от няколкото вида зеленоглави риби, срещащи се по кораловите рифове от Източна Африка и Червено море до Френска Полинезия . Подобно на други зеленоглави риби, той се храни с паразити и мъртви тъкани от кожата на по-големите риби в мутуалистични отношения , които осигуряват храна и защита за зеленоглавия рибка , както и значителни ползи за здравето на останалите риби . Забележително е и с това, че е възможно да е преминал теста с огледалото , макар че това не е безспорно.
Таксономия
Генетичен анализ на L. dimidiatus разкри, че популацията попада в две монофилетични групи. кладове , като популациите в Индийския океан обикновено имат различна ширина на ивиците от рибите в западната част на Тихия океан . Японските зеленоглави риби обаче попадат в същата група като рибите в Индийския океан, въпреки разликата във външния вид, и двата клада се припокриват около Папуа Нова Гвинея. Два тясно свързани вида чистачи, Labroides pectoralis и Labroides bicolor , са групирани в клада L. dimidiatus , така че синьоивичастият чистач може всъщност да е полифилетичен , включващ няколко вида .
Описание
Това е малък зеленоглав, средно дълъг 10 см (3,9 инча), най-много 14 см (5,5 инча). Може да се разпознае по широка надлъжна черна ивица, която минава по протежение на страната и окото; гърбът и коремът са бели (понякога леко жълтеникави). Тази бяла част променя цвета си в яркосиня отпред на животното, докато черната ивица се разширява към опашката. Малките са черни с електриковосиня линия.
Разпространение
Синьоивичатият чистач се среща по кораловите рифове в тропиците от Червено море и Индийския океан до западната част на Тихия океан (включително Папуа Нова Гвинея , Япония , Фиджи и Френска Полинезия ). [5] За първи път е регистриран в морския резерват на островите Кермадек северно от Нова Зеландия през 2015 г., след като изследователи са изследвали стотици часове неизползвани документални филмови кадри.
Почистване
Чистите рибки обикновено се срещат на почистващите станции . Почистващите станции са заети от различни групи чисти рибки, като например група млади, двойка възрастни или група женски, придружени от доминиращ мъжки. Когато посетителите се приближат до почистващите станции, чистите рибки ги поздравяват, като изпълняват танцуващо движение, при което движат задните си части нагоре и надолу. Посетителите се наричат „клиенти“. Чистачите от синьо-бели риби се почистват, за да консумират ектопаразити по рибите клиенти за храна. По-големите риби ги разпознават като чистачи, защото имат странична ивица по дължината на тялото си, и чрез моделите си на движение. Чистачите поздравяват посетителите в опит да си осигурят източник на храна и възможност за почистване с клиента. След като разпознае чистача и успешно привлече вниманието му, рибата клиент заема специфична за вида поза, за да позволи на чистача достъп до повърхността на тялото, хрилете и понякога устата си. [ необходим е цитат ] Други риби , които участват в такова поведение на почистване, включват попчета ( Elacatinus spp.) Известно е, че синьо-белият чистач почиства от семействата balaenopteridae , chondrichthyans , homaridae , octopodidae и dermochelyidae .
В различните региони, синьо-ивичатката чистачка показва различна степен на зависимост от ектопаразитите на клиентите си като основен източник на храна. В приливни среди, като например Големия бариерен риф , синьо-ивичатката чистачка е факултативен чистач, който се храни повече с корали, отколкото с рибни клиенти. Младите чистачи от синьо-бели ивици хапят клиентите си по-често от възрастните в този регион, като по този начин променят динамиката на познатата мутуалистична връзка. Въпреки това, в региони, където почистващите риби от вида „bluestreak“ зависят единствено от паразитите на клиентите си, рибите, които имат достъп до услуги за почистване, са в по-добро телесно състояние от тези, които нямат достъп до почистващи средства. В Марса Барейка в природния резерват Рас Мохамед, Египет , синьоивичатата чистачка живеят в специфични сектори на плитките рифове и е доказано, че разчитат на ектопаразити от видове като кафявата риба хирург и белокоремната дама . В този регион рибите, които посещават по-чисти риби, имат по-ниски антителни отговори от тези без достъп до по-чисти места, което предполага, че достъпът до по-чисти места може да намали необходимостта от активен имунитет.
Размножаване
Мъжките от породата чистачи защитават специфични територии за обитаване от други мъжки, в които те могат да контролират женските в тези територии. Когато доминиращият мъжки вече не съществува на тази територия, една от по-големите женски е в състояние да смени пола си, за да поеме контрол над нея.
Halichoeres chrysus , наричан обикновено канарче , златист или жълт , е вид риба от семейство Грийн. семейство , родом от централната индо-тихоокеанска област.
Описание
Канарчето е малка риба, която може да достигне максимална дължина от 12 см. Има тънко, удължено тяло с крайна уста. Оцветяването на тялото е ярко жълто с няколко вариации в зависимост от възрастта. Младите и незрелите женски имат две черни петна, оградени с бяло или светложълто по гръбната перка (първото в началото на перката (от страната на главата), а второто в средата на гръбната перка ) и трето между опашния дръжка и началото на опашната перка . Зрелите женски или младите мъжки показват само двете черни петна по гръбната перка. Зрелите мъжки показват само първото черно петно на предната част на гръбната перка, по-светло петно точно зад окото и неправилни зеленикави до розови линии по лицето.
Разпространение и местообитание
Канарският зубър е широко разпространен в тропическите и субтропичните води на централния Индо-Тихи океан , в район, граничещ с Коледните острови и Индонезия , Япония , Нов Южен Уелс и Роули Шоулс , както и с островите Тонга и Соломоновите острови .
Този рибец се среща по външните склонове на рифовете, в чакълести и песъчливи райони от повърхността до дълбочина от 30 метра.
Биология
Канарчето живее на малки групи. То е бентосно животно. хищник , който се храни главно с малки морски безгръбначни, като ракообразни , мекотели , червеи и бодлокожи, уловени върху или в субстрата.
Подобно на повечето риби, канарчето е протогинен хермафродит , т.е. индивидите започват живота си като женски с възможността по-късно да се превърнат в мъжки.

A "Designer Pair" of Amphiprion ocellaris, also known as clownfish, refers to a specific type of clownfish that has been selectively bred for unique color and pattern variations. These variations, Salvador Dali, Black Ice Snowflakes, or Snow Storms, are not naturally occurring and are the result of controlled breeding programs. These pairs are sold as a bonded unit, meaning they are two fish that the breeders have observed together and are likely to live harmoniously.
Here's a breakdown:
Selective Breeding:
Designer clownfish are the result of breeding programs that aim to produce specific color and pattern variations in the common Ocellaris clownfish.
Examples:
Black Storms are known for their black body with irregular white markings. Black Ice Snowflake clownfish are a cross between a Black Ocellaris and a Snowflake, exhibiting both black and snowflake-like patterns. Snow Storms are a result of breeding Black Storms and Black Snowflakes, displaying black fins, icy blue edges, and unique facial patterns.
Pairing:
Buying a "Designer Pair" ensures that the fish are likely to be compatible and not exhibit aggression towards each other, unlike randomly selected individual fish.
Reef Compatibility:
These designer clownfish are generally reef compatible, meaning they can be kept in a reef aquarium with corals and other invertebrates.
Symbiotic Relationship:
Clownfish are known for their symbiotic relationship with anemones, and designer strains, like their wild counterparts, can be housed with anemones like Bubble Tip anemones.
Captive Bred:
These fish are captive-bred, meaning they are raised in controlled environments, which often makes them more adaptable to aquarium life and less susceptible to diseases compared to wild-caught specimens.
The Yellow Belly Blue Tang, scientifically known as Paracanthurus hepatus, is a color variant of the popular Blue Tang, notable for its striking blue body and a yellow belly and tail. This variant also features a distinctive black marking on its upper body that forms a sort of "palette" design.
Key characteristics of the Yellow Belly Blue Tang:
Coloration: A vibrant blue body with a bright yellow tail and belly.
Markings: A black marking, shaped like a horizontal bar, extends from the back of the head, loops around the gills, and then extends back to the base of the tail.
Size: Can grow up to 8-12 inches (20-30 cm) in length.
Temperament: Generally peaceful but can become territorial and aggressive towards other tangs, especially when they mature.
Reef Compatibility: Reef safe, meaning they don't typically harm corals or other invertebrates.
Diet: Herbivorous, primarily consuming algae and marine plants.
Habitat: Found in coral reefs of the Indo-Pacific region.
Additional details:
The yellow coloration on the belly and tail is most prominent in adults, though even small juveniles may show some yellowing.
They are known for their active swimming and need a spacious aquarium with plenty of swimming room.
They are susceptible to certain diseases, particularly Ich, so maintaining good water quality and a healthy diet is crucial.
Their sharp tail spine (scalpel) is used for defense and can inflict a painful wound.
They require a varied diet, including algae-based foods, to maintain their health and reduce aggression.
The Ornate Leopard Wrasse (Macropharyngodon ornatus) is a colorful marine fish known for its intricate patterns and vibrant coloration.
