'''''Thorichthys''''' is a [genus](/source/genus) of [cichlid](/source/cichlid) fish that is native to the Atlantic slope of [Middle America](/source/Middle_America_(Americas)), ranging from southern [Veracruz](/source/Veracruz) and the [Yucatán Peninsula](/source/Yucat%C3%A1n_Peninsula) in [Mexico](/source/Mexico), to [Guatemala](/source/Guatemala) and [Honduras](/source/Honduras), with [introduced](/source/Introduced_species) populations in a few other countries.<ref name=Mahan2015>{{cite journal | author  = McMahan, C.D. | author2  = Matamoros, W.A. | author3  = Piller, K.R. | author4  = Chakrabarty, P. | name-list-style  = amp | year = 2015 | title = Taxonomy and systematics of the herichthyins (Cichlidae: Tribe Heroini), with the description of eight new Middle American Genera | journal = Zootaxa | volume = 3999 | issue = 2 | pages = 211–234 | url = http://www.mapress.com/zootaxa/2015/f/zt03999p234.pdf | doi=10.11646/zootaxa.3999.2.3 | pmid=26623572}}</ref><ref name=SFmeeki>{{cite web| title=Thorichthys meeki | url=https://www.seriouslyfish.com/species/thorichthys-meeki/ | publisher=SeriouslyFish | accessdate=28 December 2021 }}</ref> They tend to inhabit moderately-flowing to standing water such as rivers, streams, lakes, ditches and lagoons, and they are primarily freshwater fish, although ''T. helleri'' and ''T. meeki'' may occur in slightly [brackish](/source/Brackish_water) habitats.<ref name=SFmeeki/><ref>{{cite web| title=Thorichthys | url=https://www.iucnredlist.org/search?query=Thorichthys&searchType=species | publisher=[IUCN](/source/IUCN) | access-date=28 December 2021 }}</ref>

''Thorichthys'' have somewhat pointy heads and their body often has a large blackish spot, a broad dark horizontal stripe and/or a sometimes inconspicuous pattern of vertical bands. They mostly feed on [invertebrate](/source/invertebrate)s and [detritus](/source/detritus). Members of ''Thorichthys'' do not exceed {{convert|17|cm|in|abbr=on}} in [standard length](/source/standard_length),<ref name=fishbase>{{FishBase genus | genus = Thorichthys| month = July | year = 2017}}</ref> and they are popular [aquarium fish](/source/aquarium_fish), especially the well-known firemouth cichlid (''T. meeki'').<ref name=SFmeeki/> [Genetic](/source/Genetics) evidence shows that ''Thorichthys'' is most closely related to [Salvin's cichlid](/source/Salvin's_cichlid), the only species of the genus ''Trichromis'', which is [morphologically](/source/Morphology_(biology)) and behaviorally rather different. In contrast, ''Thorichthys'' is not particularly close to ''[Cribroheros](/source/Cribroheros)'' despite having several features that are similar.<ref name=Rican2016>{{cite journal|title=Diversity and evolution of the Middle American cichlid fishes (Teleostei: Cichlidae) with revised classification|author=Říčan, O.|author2=Piálek, L.|author3=Dragová, K.|author4=Novák, J.|name-list-style=amp|journal=Vertebrate Zoology|pages=1–102|volume=66|issue=1|year=2016|doi=10.3897/vz.66.e31534 |doi-access=free |url=http://www.senckenberg.de/files/content/forschung/publikationen/vertebratezoology/vz66-1/01_vertebrate_zoology_66-1_rican_1-102.pdf|accessdate=2019-01-25}}</ref>
