Лисичеликата ( Siganus vulpinus ), известна още като лисиче лице , чернолика риба заек, риба язовец или обикновена лисиче лице, е вид морска лъчеперка риба , принадлежаща към семейство Siganidae . Среща се в Индийския и Тихия океан. Може да се намери и в аквариумната търговия.
Таксономия
Заешколиката с лисича муцуна е описана за първи път официално като Amphacanthus vulpinus през 1845 г. от немските зоолози Херман Шлегел и Саломон Мюлер , катотиповото находище е дадено като остров Тернате, един от Молукските острови в Индонезия. Петнистоликата с лисича муцуна (S. unimaculatus ) се различава от S. vulpinus по това, че притежава голямо черно петно под меколъчевата част на гръбната перка . Тя е симпатрична и не е филогенетично различна и въпреки че тези два вида може да са наскоро еволюирали видове, те може да са просто цветови морфи и би трябвало да бъдат обединени под научното наименование S. vulpinus .Видовото наименование ... vulpinus означава „подобен на лисица“, Шлегел и Мюлер не обясниха за какво се има предвид това, но се смята, че става въпрос за заострената муцуна.
Описание
Заешколиката с лисича лика има компресирано тяло, чиято дълбочина се вписва в стандартната ѝ дължина 1,9 до 2,4 пъти. Гръбният профил на главата е стръмен към задната част на окото и има вдлъбнатина между очите и тръбеста муцуна. Опашната перка е слабо раздвоена. Има изпъкнал шип в областта на тила към предната част на гръбната перка. Както всички заешколики, гръбната перка има 13 бодла и 10 меки лъча, докато аналната перка има 7 бодла и 9 меки лъча. Бодлите на перките съдържат отровни жлези. Този вид достига максимална обща дължина от 25 см (9,8 инча), въпреки че 20 см (7,9 инча) е по-типична. Основният цвят на тази заешколика е ярко жълт с бяло по главата и предната част на тялото, но лисичколиките могат да се камуфлират, когато са заплашени, като бързо променят цвета си в тъмнокафяв. Има черна ивица, която се простира назад от устата през окото до началото на гръбната перка, а на гърдите има черна област, която се простира нагоре до точно над основата на гръдната перка, като се стеснява.
Разпространение и местообитание
Лисичният заек се среща в далечния източен Индийски океан и в западната част на Тихия океан от Индонезия до островите Маршал и Гилбърт на север чак до Тайван и на юг до Нова Каледония и Австралия. [1] В Австралия се среща от Западна Австралия по северните рифове и офшорните рифове, при рифа Ашмор в Тиморско море и на източното крайбрежие на Куинсланд от северния Голям бариерен риф до островите Козирог . Регистрирана е на дълбочина до 30 м (98 фута). [1] Този вид живее в лагуни и морски рифове, където има богат растеж на корали.
Биология
Рибата заек с лисичи лик е всеядна, яде предимно водорасли и зоопланктон. Тя може да бъде териториална, възрастните обикновено се срещат поединично или по двойки и са свързани с разклоняващи се корали Acropora . Младите и подвъзрастните индивиди понякога могат да образуват големи пасажи, хранейки се с водорасли, растящи в основата на коралите Acropora. Този вид произвежда отрова в бодлите на перките си. В изследване на отровата на сроден вид е установено, че отровата на рибата заек е подобна на отровата на каменните риби .
Използване
Заешколиката лисича се появява в аквариумната търговия. Не се води статистика за улова и в някои райони този вид се появява в смесени улови на рифови риби, уловени чрез подводен риболов .
Signigobius biocellatus, известен още като Двойнопетнисто попче или Очнопетнисто попче, е вид попче, което често живее по двойки. Двойките обикновено споделят една дупка и проявяват уникално поведение на „подскачане“, с големите си, жълто обкръжени оцели (очи) на гръбните си перки и черни тазови и анални перки, наподобяващи клещи. Те са известни с бледото си тяло с кафяви петна и тясна кафява лента през окото.
Ето по-подробно описание:
Външен вид:
Двупетнистите попчета имат бледо тяло с неправилни кафяви петна и седла в горната половина и три неправилни кафяви ивици в долната половина. Тясна кафява ивица преминава през основата на опашната перка. Тазовите и аналните им перки са черни със сини петна.
Поведение:
Те често се носят ниско над пясъка и си сигнализират с оцелите си. Могат да бъдат агресивни към други видове попчета, но предпочитат да живеят поотделно или по двойки.
Местообитание:
Те обитават лагуни и крайбрежни заливи с тинест субстрат и се разпростират сред корали и рифови отломки, до дълбочина от 30 метра.
Развъждане:
Двупетнистите попчета могат да се развъждат в плен. В дивата природа двойките работят заедно, за да създават и поддържат дупки. Мъжкият понякога се запечатва в дупката по време на хвърляне на хайвера и двойката може от време на време да се връща в дупката за поддръжка.
The Ocellated dragonet (Synchiropus ocellatus) is a small, colorful fish with a distinctive diamond-shaped body when viewed from above, and is known for its unique way of moving along the substrate using its pectoral fins. It typically grows to about 8 centimeters (3.1 inches) in length. Males are generally more brightly colored than females and have a large, sail-like dorsal fin, often orange at the base. The body is mottled with brown and white, sometimes with red highlights, and features a pattern of stripes or spots.
Here's a more detailed breakdown:
Appearance:
The fish has a mottled brown and white body, sometimes with red highlights. It has a large, boxy head and a diamond-shaped body when viewed from above.
Size:
It reaches a maximum length of about 8 centimeters (3.1 inches).
Coloration:
Males are generally more colorful than females, with a bright orange dorsal fin base. They also have a distinctive pattern of stripes or spots on their body.
Locomotion:
The Ocellated dragonet uses its pectoral fins to shuffle along the substrate, rather than swimming in a typical fish-like manner.
Habitat:
They are found in shallow waters, particularly on sandy areas of reefs and in tide pools.
Diet:
They are micropredators, feeding on small benthic invertebrates and zooplankton.
Aquarium Care:
In aquarium settings, they are known to be reef-safe, hardy, and stay small, making them popular with aquarists. However, they require a well-established aquarium with a constant supply of live zooplankton or other small foods, as they cannot eat large meals at once.

Lighting Duration:
12 hours is sufficient for growing macroalgae. The LED lighting is running on a reverse cycle so that when the main tank lights are off the LED lights turn on. During the night time, photosynthesis stops inside your aquarium and corals will no longer uptake CO2. This leaves an increased amount of CO2 dissolved in your aquarium water which then lowers your pH level. By running the Macroalgae Reactor at night, the algae inside the reactor will continue to uptake CO2 and help reduce the pH swing. This will help to stabilize the pH levels and the overall safety of its inhabitants.
Macroalgae Grows:
It's important to periodically harvest a portion by removing it from the Macroalgae Reactor. This opens up space for new macroalgae to grow and to continue absorbing undesirable nutrients

Stylophora pistillata, commonly called smooth cauliflower coral or hood coral, is a species of stony coral in the Indo-Pacific region. It has a branching growth form, with blunt-ended branches that thicken and become more massive as the colony matures. Corallites (the individual polyps' stony cups) are conical or hooded and partially submerged in the coenosteum (the stony framework of the colony). These corallites have a prominent, solid columella (the central column) and may have six primary and sometimes six secondary septa (stony plates forming the corallite wall). The coenosteum is covered in fine spinules. Colonies can be cream, pink, bluish, or green.
Key features of Stylophora pistillata:
Growth Form: Branching, with branches becoming thick and submassive.
Corallites: Conical or hooded, with a prominent columella and septa.

Color: Cream, pink, bluish, or green.
Habitat: Shallow water reef environments exposed to strong wave action.
Distribution: Indo-Pacific region
Symphyllia is a genus of large polyp stony (LPS) corals, characterized by their massive, dome-shaped or flat colonies with meandroid (brain-like) corallites. These corals are known for their diverse colors and patterns, often with contrasting colors between valley floors and walls. While the genus name Symphyllia is no longer taxonomically valid, with most species now classified under Lobophyllia, it's still used for CITES purposes.
Key characteristics of Symphyllia:
Colony Shape: Typically massive, dome-shaped, or flat, with meandroid valleys.
Corallites: Flabello-meandroid (brain-like), with ridges separating valleys, often with contrasting colors.
Polyps: Each corallite houses multiple polyps, indicated by the many mouth openings.
Color: Wide range of colors, often mottled, with contrasting colors between valley floors and walls.
Tentacles: They have long sweeper tentacles that can extend to sting other corals.
Habitat: Found on reef slopes and in protected areas of reefs.
Taxonomy: While the genus Symphyllia is no longer valid, it's still used for CITES (Convention on International Trade in Endangered Species) purposes, and many species have been reassigned to Lobophyllia.
Examples of Symphyllia species:
Symphyllia valenciennesi (now often classified under Lobophyllia), Symphyllia wilsoni (now often classified under Australophyllia), Symphyllia radians, Symphyllia agaricia, and Symphyllia recta.
Distinguishing Symphyllia from Lobophyllia:
Corallite Size and Structure:
Symphyllia species generally have larger, more branched corallites with more mouth openings compared to Lobophyllia.
Valley Ridges:
Symphyllia corallites often exhibit ridges dividing the interior surface (like a brain coral), while Lobophyllia corallites are often more separated.
