Cichliformes
Cichliformes is an order of fishes. Its members were previously classified under the order Perciformes, but now many authorities consider it to be an independent order within the subseries Ovalentaria. Families There are two families within the Cichliformes; the convict blennies are a small family consisting of a single genus and two species, while the cichlids are one of the largest vertebrate families with over 202 genera and more than 1700 species. It is molecular data which placed the two seemingly dissimilar families in the same taxon. The families are: * Pholidichthyidae D.S. Jordan, 1896 (Convict blennies) * Cichlidae Cichlids are fish from the family Cichlidae in the order Cichliformes. Cichlids were traditionally classed in a suborder, the Labroidei, along with the wrasses ( Labridae), in the order Perciformes, but molecular studies have contradicted thi ...

Cichlid
Cichlids are fish from the family Cichlidae in the order Cichliformes. Cichlids were traditionally classed in a suborder, the Labroidei, along with the wrasses ( Labridae), in the order Perciformes, but molecular studies have contradicted this grouping. The closest living relative of cichlids is probably the convict blenny, and both families are classified in the 5th edition of ''Fishes of the World'' as the two families in the Cichliformes, part of the subseries Ovalentaria. This family is both large and diverse. At least 1,650 species have been scientifically described, making it one of the largest vertebrate families. New species are discovered annually, and many species remain undescribed. The actual number of species is therefore unknown, with estimates varying between 2,000 and 3,000. Many cichlids, particularly tilapia, are important food fishes, while others, such as the ''Cichla'' species, are valued game fish. The family also includes many popular freshwater aquariu ...

Ovalentaria
Ovalentaria is a clade of ray-finned fishes within the Percomorpha, referred to as a subseries. It is made up of a group of fish families which are referred to in ''Fishes of the World's'' fifth edition as'' incertae sedis'', as well as the orders Mugiliformes, Cichliformes, and Blenniiformes. It was named by W. L. Smith and T. J. Near in Wainwright ''et al.'' (2012) based on a molecular phylogeny, but the authors suggested that the group was united by the presence of demersal eggs that are attached to a substrate. Some authors have used the ordinal name Stiassnyiformes for a clade including Mugiloidei, Plesiopidae, Blenniiformes, Atherinomorpha, and Cichlidae, and this grouping does appear to be monophyletic. Classification In the 5th edition of'' Fishes of the World'', the Ovalentaria are classified as: * ''incertae sedis'' ** Family Ambassidae (Asian glassfishes) ** Family Embiotocidae (surfperches) ** Family Grammatidae (basslets) ** Family Plesiopidae (roundheads) ** F ...

Pholidichthyidae
''Pholidichthys'' is a genus of ray-finned fish which consists of two species of the tropical Pacific Ocean. It is the only genus in the family Pholidichthyidae, one of two families in the order Cichliformes. Species The following two species are found within this genus and family: * '' Pholidichthys anguis'' Springer & Larson, 1996 * ''Pholidichthys leucotaenia ''Pholidichthys leucotaenia'', commonly known as the convict blenny/goby or the engineer blenny/goby, is a marine fish from the west-central Pacific Ocean.

Pholidichthys Leucotaenia
''Pholidichthys leucotaenia'', commonly known as the convict blenny/goby or the engineer blenny/goby, is a marine fish from the west-central Pacific Ocean. Despite its common names, it is neither a blenny nor a goby, but is in fact one of two species in the family Pholidichthyidae. Description A small eel-shaped fish, it can grow up to in length. Juveniles resemble the striped catfish ''Plotosus lineatus'', which is venomous, having a black body with a white dorsal stripe. As they develop, the stripe changes to white convict-style barring or spotting in the adult. Ecology ''P. leucotaenia'' lives in shallow lagoons and on coastal reefs from the Philippines to the Solomon Islands. It is often found in schools under ledges or around coral heads. These schools swim in such tight formations, they resemble a single organism. Occasionally, the species is found in the aquarium trade, where it is known for disrupting all but the most stable structures. DNA analyses show this species ...

Early Cretaceous
The Early Cretaceous ( geochronological name) or the Lower Cretaceous (chronostratigraphic name), is the earlier or lower of the two major divisions of the Cretaceous. It is usually considered to stretch from 145 Ma to 100.5 Ma. Geology Proposals for the exact age of the Barremian-Aptian boundary ranged from 126 to 117 Ma until recently (as of 2019), but based on drillholes in Svalbard the defining early Aptian Oceanic Anoxic Event 1a (OAE1a) was carbon isotope dated to 123.1±0.3 Ma, limiting the possible range for the boundary to c. 122–121 Ma. There is a possible link between this anoxic event and a series of Early Cretaceous large igneous provinces (LIP). The Ontong Java-Manihiki-Hikurangi large igneous province, emplaced in the South Pacific at c. 120 Ma, is by far the largest LIP in Earth's history. The Ontong Java Plateau today covers an area of 1,860,000 km2. In the Indian Ocean another LIP began to form at c. 120 Ma, the Kerguelen P ...

Pterophyllum Scalare
''Pterophyllum scalare'', most commonly referred to as angelfish or freshwater angelfish, is the most common species of ''Pterophyllum'' kept in captivity. It is native to the Amazon Basin in Peru, Colombia, and Brazil. Particularly to the Ucayali River, Ucayali river in Peru, the Oyapock River in French Guiana, the Essequibo River in Guyana, the Solimões River, Solimões, the Amapá, and the Amazon rivers in Brazil. It is found in swamps or flooded grounds where vegetation is dense and the water is either clear or silty. Its native water conditions range from a pH of 7.0 to 6.0, a water hardness range of 3 to 10 °dH, and water temperature ranging from 26 to 30 °C (75 to 86 °Fahrenheit, F). This is the species of angelfish most frequently found in the aquarium trade. A similar (cross-breeding possible) ''P. scalare'' exists in the Orinoco. They are of the same size and shape, the only difference being its stripes: the Orinoco ''P. scalare'' has thinner, but dual stri ...

Cichla Ocellaris
''Cichla ocellaris'', sometimes known as the butterfly peacock bass ("peacock bass" is also used for some of its relatives), is a very large species of cichlid from South America, and a prized game fish. It reaches in length. It is native to the Marowijne and Essequibo drainages in the Guianas, and the Branco River in Brazil. It has also been introduced to regions outside its natural range (e.g., Florida, Hawaii, and Puerto Rico), but some uncertainty exists over the exact identity, and at least some of the introductions may involve another ''Cichla'' species or hybrids.Nico, L. (2011). Cichla ocellaris.' USGS Nonindigenous Aquatic Species Database, Gainesville, FL. It is frequently confused with '' C. monoculus''. Studies conclude that the introduction of ''Cichla ocellaris'' does not negatively impact fish communities in Florida, making it an effective fisheries management tool.Shafland, P. L. (1999).

Order (biology)
Order ( la, wikt:ordo#Latin, ordo) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between Family_(biology), family and Class_(biology), class. In biological classification, the order is a taxonomic rank used in the classification of organisms and recognized by the nomenclature codes. An immediately higher rank, superorder, is sometimes added directly above order, with suborder directly beneath order. An order can also be defined as a group of related families. What does and does not belong to each order is determined by a taxonomist, as is whether a particular order should be recognized at all. Often there is no exact agreement, with different taxonomists each taking a different position. There are no hard rules that a taxonomist needs to follow in describing or recognizing an order. Some taxa are accepted almost universally, while others are recognized only rarely. The name of an order is usually written with a capital letter. Fo ...

Perciformes
Perciformes (), also called the Percomorpha or Acanthopteri, is an order or superorder of ray-finned fish. If considered a single order, they are the most numerous order of vertebrates, containing about 41% of all bony fish. Perciformes means "perch-like". Perciformes is an Order within the Clade Percomorpha consisting of "perch-like" Percomorphans. This group comprises over 10,000 species found in almost all aquatic ecosystems. The order contains about 160 families, which is the most of any order within the vertebrates. It is also the most variably sized order of vertebrates, ranging from the ''Schindleria brevipinguis'' to the marlin in the genus ''Makaira''. They first appeared and diversified in the Late Cretaceous. Among the well-known members of this group are perch and darters (Percidae), sea bass and groupers (Serranidae). Characteristics The dorsal and anal fins are divided into anterior spiny and posterior soft-rayed portions, which may be partially or compl ...
