Labidochromis Caeruleus
''Labidochromis caeruleus'' is a species of cichlid endemic to the central western coastal region of Lake Malawi in East Africa. It is also known as lemon yellow lab, the blue streak hap, the electric yellow or yellow prince, depending on the colour morph. A naturally occurring yellow-coloured variant from Lion's Cove is one of the most popular cichlids amongst aquarium hobbyists. Electric yellows inhabit water with a pH between 7.8 and 8.9 and an ideal temperature range of 23–26 °C (73.4–78.8 °F). Large males may reach in length. Reproduction This species, like the ''Astatotilapia burtoni'', is a maternal mouthbrooder, meaning the eggs are carried, hatch, and develop in the mother's mouth (buccal cavity), for about three weeks. These fish are ovophiles and the male will excavate a pit in the sand within his territory, in which the female lays the eggs; the female then takes these eggs into her mouth for fertilization.

Electric Yellow Cichlid
200px, Mature male electric yellow cichlid The electric yellow cichlid is a popular freshwater aquarium fish. It is a naturally occurring variant of ''Labidochromis caeruleus'' endemic to the central western coastal region of Nkhata Bay in Lake Malawi in East Africa. It is the most popular African cichlid amongst aquarium hobbyists. These fish are mouthbrooders; the female lays her eggs on the surface of rocks and then scoops them into her mouth where they brood for 18 days before being released. The electric yellow cichlid is set apart from other African cichlids by its striking electric yellow coloration. Mature specimens flaunt contrasting black stripes and vertical bars. The electric yellow African cichlid is also known colloquially as the yellow lab or electric yellow lab. Considered a newer species and referred to commercially as Labidochromis tanganicae, this cichlid lives in the waters of Lake Malawi between the islands of Charo and Mbowe.

Mouthbrooder
Mouthbrooding, also known as oral incubation and buccal incubation, is the care given by some groups of animals to their offspring by holding them in the mouth of the parent for extended periods of time. Although mouthbrooding is performed by a variety of different animals, such as the Darwin's frog, fish are by far the most diverse mouthbrooders. Mouthbrooding has evolved independently in several different families of fish. Mouthbrooding behaviour Paternal mouthbrooders are species where the male looks after the eggs. Paternal mouthbrooders include the arowana, various mouthbrooding bettas and gouramies such as ''Betta pugnax'', and sea catfish such as ''Ariopsis felis''. Among cichlids, paternal mouthbrooding is relatively rare, but is found among some of the tilapiines, most notably the black-chin tilapia ''Sarotherodon melanotheron''. In the case of the maternal mouthbrooders, the female takes the eggs. Maternal mouthbrooders are found among both African and South American ci ...

Labidochromis
''Labidochromis'' is a genus of cichlid fishes that are endemic to Lake Malawi in East Africa. The genus includes 18 formally described species, and several yet undescribed species. It includes a number of species commonly kept in cichlid aquariums such as '' L. caeruleus'' (electric yellow). The species in this genus can easily hybridize, so if kept in an aquarium it is recommended to only have one species from this genus. Species There are currently 18 recognized species in this genus: * ''Labidochromis caeruleus'' Fryer, 1956 (Blue streak hap) * '' Labidochromis chisumulae'' D. S. C. Lewis, 1982 * '' Labidochromis flavigulis'' D. S. C. Lewis, 1982 (Chisumulu pearl) * '' Labidochromis freibergi'' D. S. Johnson, 1974 * ''Labidochromis gigas'' D. S. C.

Spirulina (dietary Supplement)
Spirulina is a biomass of cyanobacteria (blue-green algae) that can be consumed by humans and animals. The three species are '' Arthrospira platensis'', ''A. fusiformis'', and ''A. maxima''. Cultivated worldwide, ''Arthrospira'' is used as a dietary supplement or whole food. It is also used as a feed supplement in the aquaculture, aquarium, and poultry industries.Vonshak, A. (ed.). ''Spirulina platensis (Arthrospira): Physiology, Cell-biology and Biotechnology.'' London: Taylor & Francis, 1997. Etymology and ecology The species ''A. maxima'' and ''A. platensis'' were once classified in the genus ''Spirulina''. The common name, spirulina, refers to the dried biomass of ''A. platensis'', which belongs to photosynthetic bacteria that cover the groups Cyanobacteria and Prochlorophyta. Scientifically, a distinction exists between spirulina and the genus ''Arthrospira''. Species of ''Arthrospira'' have been isolated from alkaline brackish and saline waters in tropical and subtro ...

Neon Tetra
The neon tetra (''Paracheirodon innesi'') is a Freshwater fish of the characin family (family Characidae) of order Characiformes. The type species of its genus, it is native to blackwater and clearwater streams in the Amazon basin of South America. Its bright colouring makes the fish visible to conspecifics in the dark blackwater streams, and is also the main reason for its popularity among freshwater fish hobbyists, with neon tetras being one of the most widely kept tropical fish in the world. Range and habitat The neon tetra is found in the western and northern Amazon basin in southeastern Colombia, eastern Peru, and western Brazil. It lives in waters with a temperature between and pH 4–7.5. It has a preference for acidic blackwater streams, but also occurs in transparent clearwater streams. It is not found in the whitewater rivers. UN FAO considers ''P. innesi'' an introduced species in Singapore and the United States. FAO considers its introduction to Singapore to ...

Zebra Danio
The zebrafish (''Danio rerio'') is a freshwater fish belonging to the minnow family (Cyprinidae) of the order Cypriniformes. Native to South Asia, it is a popular aquarium fish, frequently sold under the trade name zebra danio (and thus often called a "tropical fish" although both tropical and subtropical). It is also found in private ponds. The zebrafish is an important and widely used vertebrate model organism in scientific research, for example in drug development, in particular pre-clinical development. It is also notable for its regenerative abilities, and has been modified by researchers to produce many transgenic strains. Taxonomy The zebrafish is a derived member of the genus '' Brachydanio'', of the family Cyprinidae. It has a sister-group relationship with ''Danio aesculapii''. Zebrafish are also closely related to the genus ''Devario'', as demonstrated by a phylogenetic tree of close species. Distribution Range The zebrafish is native to fresh water habi ...

Mbuna
Mbuna (pronounced Mmm-boo - nah ) is the common name for a large group of African cichlids from Lake Malawi, and are members of the haplochromine family. The name ''mbuna'' means "rockfish" in the language of the Tonga people of Malawi.Loiselle Paul V. (1988) ''A Fishkeepers Guide to African Cichlids.'' p 97. Salamander Books, London & New York, . As the name implies, most mbuna are cichlids that live among the piles of rocks and along the rocky shores of Lake Malawi, as opposed to the utaka, cichlids that live in the open water or on sandy shores or soft substrates. Some species of mbuna are highly sexually dimorphic, although many are not. Among biologists, almost all of the cichlid species of Lake Malawi, including mbuna and non mbuna such as the utaka, are believed to have descended from one or a very few species that became isolated in the lake. With rising water levels, new habitats could be colonized and the many isolated rocky outcrops allowed new mbuna species to form.G ...

Fertilization
Fertilisation or fertilization (see spelling differences), also known as generative fertilisation, syngamy and impregnation, is the fusion of gametes to give rise to a new individual organism or offspring and initiate its development. Processes such as insemination or pollination which happen before the fusion of gametes are also sometimes informally called fertilisation. The cycle of fertilisation and development of new individuals is called sexual reproduction. During double fertilisation in angiosperms the haploid male gamete combines with two haploid polar nuclei to form a triploid primary endosperm nucleus by the process of vegetative fertilisation. History In Antiquity, Aristotle conceived the formation of new individuals through fusion of male and female fluids, with form and function emerging gradually, in a mode called by him as epigenetic. In 1784, Spallanzani established the need of interaction between the female's ovum and male's sperm to form a zygote in frog ...

Ovophile
Ovophiles are mouthbrooding members of the fish family Cichlidae (cichlids). Ovophiles dig pits or holes in which the female lays eggs. The female lays eggs in this pit and then immediately takes the eggs into her mouth. The male then fertilizes the eggs in the female's mouth. In some species, the male's anal fin is covered with circular markings that, to a female, look confusingly like eggs. Female will attempt to bring the male's tail into their mouth and, at the right moment, the male will ejaculate into their mouths, fertilizing the eggs. Examples including the include the '' Aulonocara'', ''Haplochromis'' and ''Pseudotropheus'', and ''Labidochromis caeruleus ''Labidochromis caeruleus'' is a species of cichlid endemic to the central western coastal region of Lake Malawi in East Africa. It is also known as lemon yellow lab, the blue streak hap, the electric yellow or yellow prince, depending on the co ...''.

Astatotilapia Burtoni
''Astatotilapia burtoni'' is a species of fish in the family Cichlidae. It is found in Lake Tanganyika and its surrounding waterways, including parts of Burundi, Rwanda, Tanzania, and Zambia. Its natural habitats are rivers, intermittent rivers, swamps, freshwater lakes, freshwater marshes, intermittent freshwater marshes, and inland deltas. ''Astatotilapia burtoni'' has been used as a model organism to study the behaviors and physical systems of cichlids, including their development and embryogenesis. Moreover, the phylogenetic position of this particular species makes it an ideal model system for comparative genomic research. ''A. burtoni'' belongs under the haplochromines, which is the lineage of cichlids with the most species, and has been discovered to be a sister group to both the Lake Victoria region superflock (which has about 600 species) and the species flock of Lake Malawi (which has about 1,000 species).
