The convict cichlid (Amatitlania nigrofasciata) is a fish species from the family Cichlidae, native to Central America, [3] also known as the zebra cichlid. [4] Convict cichlids are popular aquarium fish [ 3 ] and have also been the subject of numerous studies on fish behaviour.
Amatitlania coatepeque, the Lago Coatepeque convict cichlid, is a freshwater fish species endemic to El Salvador. [1] The species was first identified in 1924 and takes its name from Lake Coatepeque in the interior highlands of western El Salvador.
The convict cichlid has sometimes been placed within the genus Cryptoheros as well, but is now considered a member of the genus Amatitlania. [3] [4] Several other species such as Amatitlania septemfasciata and Amatitlania sajica had also once been included within Cryptoheros. [2] FishBase currently recognizes four species in this genus: [1]

[40] While an uptick in research on bird homosexuality – and animal homosexuality in general – has been coming out in recent years, it is common for some authors to labour in articulating the view any root cause or function of bird homosexuality is poorly understood.
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 convict julie (Julidochromis regani) is a cichlid species in the subfamily Pseudocrenilabrinae family endemic to Lake Tanganyika. Hence it is found in Burundi, the Democratic Republic of the Congo, Tanzania, and Zambia. The fish is named after Charles Tate Regan. [2] This species is closely related to Julidochromis marlieri.

[2] [3] These cichlid can be identified by black melanin-based stripes in males and an additional bright orange spot on the abdomen for females. [4] The size and pigmentation of the spots and stripes respectively correlate to proactivity within this cichlid.
