It is a Rio Grande Cichlid or Texas Cichlid. H. cyanoguttatus was recorded to be established in Six Mile Creek in Hillsborough County (the population may have been extirpated since) with the source of this introduction possibly a fish farm that cultured the species as an aquarium fish during the 1940s and early 1950s under the trade name 'Texas bluespot' (Courtenay and Hensley, 1979; Nico et al., 2015). Rio Grande Cichlid is known for its cream and turquoise spots giving them a speckled look over a very dark to light olive background coloration. Herichthys cyanoguttatus Texas Cichlid. The fighting tactics of male mouthbrooding cichlids: the effects of size on residency. Rio Grande, Brownsville, Texas. Cichlids are superficially similar to North American native sunfishes (Lepomis spp.) The sides of the fish are frequently patterned in shades of green, red, brown, and blue. These common names may refer to colour variants of H. cyanoguttatus as well as to hybrids and entirely different species. Mills D; Vevers G, 1989. Texas cichlids are native to lakes and rivers in south Texas and northern Mexico, making them the most northern naturally occurring species of cichlid in the world. Molecular Phylogenetics and Evolution, 31(2):754-764. It is the only native cichlid in the U.S. and amongst the first cichlids imported to Europe, having first been imported in 1912. In Mexico, Herichthys species, including both H. cyanoguttatus and H. carpintis, are considered legitimate food fish. San Antonio River Authority biologists in Texas have observed that H. cyanoguttatus will displace native Centrarchidae in stressed habitats and dominate the ecosystem (Gonzales and Moran, 2005). Adult males also develop a nuchal hump on their head. Animal Behaviour, 47:655-662. These research findings are supported by Lorenz (2008) and Lorenz et al. Breeding adults have a white head and front half of the body, and the rear half of the body, particularly the ventral surface, is black (Page and Burr, 1991; Berg, 2010). Lorenz OT; O'Connell MT, 2011. © Copyright 2021 CAB International. Although breeding pairs will attack most other fishes in the vicinity of the nest, attacks are more pronounced against conspecifics. New and little-known reptiles and fishes in the museum collections. Atlas of North American freshwater fishes. > 0°C, dry winters), Salinities of up to 16 ppt had no significant effect on growth in the laboratory therefore short/long term tolerance is likely to be higher (Lorenz, 2008), Lower lethal temperature of 5°C recorded in laboratory (Shafland and Pestrak, 1982), Herichthys cyanoguttatus Baird and Girard, 1854, Cichlasoma cyanoguttatum Baird and Girard, 1854, Herichthys cyanoguttatum Baird and Girard, 1854, Parapetenia cyanostigma Hernandez-Rolon, 1990, Highly adaptable to different environments, Capable of securing and ingesting a wide range of food, Benefits from human association (i.e. Also introduced and established in parts of Florida (population may have been extirpated) and Louisiana (population is extensive), Aw - Tropical wet and dry savanna climate, < 60mm precipitation driest month (in winter) and < (100 - [total annual precipitation{mm}/25]), Cs - Warm temperate climate with dry summer, Warm average temp. Seriously Fish. Identification: . The majority of introductions of the species in the USA are thought to have resulted from the release of aquarium fishes (Nico et al., 2015). Tomelleri and Eberle (1990) report that the species can only survive cool winters in the ‘cooling lakes’ of power plants or in rivers near the outlets of warm springs at the northern limit of its distribution in the Edwards Plateau, Texas, USA.

Interspecific aggression of an invasive cichlid species and native bluegill. Shafland and Pestrak (1982), reported a lower lethal temperature of 5°C under experimental conditions. Rio Grande cichlids are an invasive species that has spread throughout the metropolitan New Orleans area. The utilization of saline environments to facilitate the spread of freshwater fish species has been referred to as using ‘saline bridges’ and was proposed as a possible mechanism to help explain the wide spread of Sander lucioperca through Europe (Brown et al., 2001). Lee et al. These fish may grow to exceed 10 inches in length. Buchanan (1971) reported that in the San Marcos River, Texas, H. cyanoguttatus reproduced from March to August with peak activity in April. Boston, USA: Houghton Mifflin Company, 432 pp. Tomelleri JR; Eberle ME, 1990. http://nas.er.usgs.gov/default.aspx. These little monsters are harmless, but you will freak out over them. The Rio Grande or Texas cichlid Herichthys cyanoguttatus is a popular ornamental freshwater fish that has been introduced to a number of US states. Blue tilapia are also known to impact a number of minnows and topminnows such as shiners, chub, pupfish, and mosquitofish -- including some imperiled species -- through habitat degradation, competition for incidental consumption of eggs through herbivory, predation on small and/or young fishes, and distu… Detailed coverage of invasive species threatening livelihoods and the environment worldwide. by Reis RE, Kullander SO, Ferraris CJ]. Miller RR; Minckley LW; Norris SM, 2005. The Texas Cichlid Herichthys cyanoguttatus (previously Cichlasoma cyanoguttatum) is the northern most occurring cichlid and the only cichlid native to waters of the United States.It is naturally found in the waters of southern Texas ( namely the Rio Grande) and northern Mexico. FishBase. In Louisiana, USA, H. cyanoguttatus has been collected from bayous and canals in the New Orleans metropolitan area (Lorenz, 2008; Lorenz and O'Connell, 2011) and a few isolated specimens have been collected from different areas including Lake Pontchartrain, Orleans Parish (Nico et al., 2015). in Mexico, and Moravec (1998) reported that H. cyanoguttatus was host to many parasitic infestations in the Upper San Marcos River in Texas, USA. H. cyanoguttatus is a moderately popular ornamental fish species maintained by hobbyists worldwide.

There are several small black spots at the base of the caudal fin and along the middle, rear half of the body. The Texas Cichlid also called the Rio Grande Perch and the Rio Grande Cichlid is an iridescent golden coloration with pearl highlights and white dots on its body and fins. Physiological effects of saline waters on zander. Serum samples were obtained by the method of Koehn (1969). Originally from the western Gulf of Mexico. Rio Grande Cichlid Also known as the Texas cichlid, this freshwater species is the only cichlid native to the United States. by Lee DS].

Since about 1995, the Rio Grande cichlid is becoming more common in the waters in and around New Orleans. H. cyanoguttatus may be distinguished from the closely-related H. carpintis by the larger spots of the background coloration of the latter species (Berg, 2010). The Aquarium, 7(8):128-130.

An annotated checklist of freshwater fishes of Texas, with key to identification of species, 43(4):1-56. (2004) listed H. cyanoguttatus as host to the following parasites: Crassicutis cichlasomae, Centrocestus formosanus, Clinostomum complanatum, Diplostomum sp., Posthodiplostomum minimum, Bothriocephalus acheilognathi, Neoechinorhynchus golvani, Rhabdochona kidderi and Contracaecum sp. Both parents are active in guarding the eggs and fry though the male and female alternate in the performance of parental responsibilities. Journal of Ethology, 29(1):39-46. H. cyanoguttatus is one of the most cold-tolerant cichlids. Their native range includes most of the Rio Grande drainage and south into northeastern Mexico, but they have been introduced throughout Texas, where they are well-established in the Edwards Plateau and coastal drainages eastward to Houston. Female and male Texas cichlids (Herichthys cyanoguttatus) do not fight by the same rules. (2002) found that H. cyanoguttatus was host to many parasitic infestations (protozoa, worms, etc.) The species was reportedly first introduced into Florida from Texas stocks around 1941 by a private individual from Mulberry, Polk County (Courtenay and Hensley, 1979). Moravec F, 1998. Lorenz OT; Schofield PJ; O'Connell MT, 2011. Fontaine PA, 1938.

Lorenz OT; O'Connell MT, 2008. Fish and Wildlife Service, Gainesville, FL. H. cyanoguttatus is diurnal and non-migratory (Froese and Pauly, 2015). Body oval, moderately compressed; large fish with a bulbous hump over the eyes; 1 pair of nostrils; mouth short, oblique, horizontal or slightly down pointing; jaws about equal or upper projecting; top jaw highly protrusible; jaw teeth mostly conical, but central teeth of outer series compressed and spatula-like in adult, closely packed and pointed in young; gill rakers 7-15; dorsal fin XV-XVIII, 10-14, without a notch between spines and rays; anal fin V-VI, 7-11; pectoral fin reaching to above anus; length of tail base < its depth at its mid-point; bases of soft dorsal and anal fins scaled; lateral line in 2 straight overlapping sections; scales large, 18+8 on lateral line. Due to the variable regulations around (de)registration of pesticides, your national list of registered pesticides or relevant authority should be consulted to determine which products are legally allowed for use in your country when considering chemical control. Known as the Texas Blue in the aquarium trade, this fish breeds readily in aquaria, and a number of folks have admitted to dumping excess fish into the canals. Robertson MS; Winemiller KO, 2003. In Florida, USA, H. cyanoguttatus has been collected from several locations in Tampa as early as the 1940s (Nico et al., 2015). 28 (2), 221-224. The Texas cichlid Herichthys cyanoguttaus. 432 pp. Laboratory intraspecific behavioural studies have shown that H. cyanoguttatus is aggressive as an invader into the territory of heterospecifics, and also as a territorial holder or resident (Turner, 1994, Draud et al., 2004). Lorenz (2008) also provided anecdotal field observations of agonistic behaviour between H. cyanoguttatus and largemouth bass (Micropterus salmoides), western mosquitofish (Gambusia affinis), sailfin mollies (Poecilia latipinna) and blue crabs (Callinectes sapidus). Breeding season Rio Grande leopard frogs can reproduce all year round, but most often reproduce in the spring and fall. Ecological Threat: Blue Tilapia have been found to negatively impact fish populations and degrade habitat. Hubbs C, Lucier T, Garrett GP, Edwards RJ, Dean SM, Marsh E, Belk D, 1978.

Common Names: Texas cichlid, Rio Grande cichlid, pearl cichlid, Rio Grande perch Type Locality: Brownsville, Texas Range: Lower Rio Grande drainage in Texas, south into northwestern Mexico. Mire (2001, referenced in Lorenz, 2008) recorded that agonistic behaviour of H. cyanoguttatus may cause the reproductive failure of native sheepshead minnows (Cyprinodon variegatus) in experimental pools. The Rio Grande Cichlid (Cichlasoma cyanoguttatum) is a moderately sized species of freshwater fish that occurs in the Rio Grande and Pecos River basins of west central Texas. Garman S, 1881. First posted by C. Dean Wilson 2012 Northern Rio Grande Early Plain Gray refers here to utility wares with completely smoothed surfaces that may occur at sites in the Northern Rio Grande region dating to most prehistoric periods, although their relative frequency within ceramic assemblages changed significantly across components dating to different periods.

The most common form is ovate and somewhat laterally compressed, but some species are strongly compressed or cylindrical and elongated. Cichlasoma, Greek for "body of a wrasse," a similar type of fish; cyanoguttatum Greek for "blue-spotted" (Tomelleri and Eberle 1990). It has also been introduced into the Concho, Nueces, lower Brazos, San Marcos Rivers, Town Lake Reservoir (in southeast Austin), Lake Houston, West Matagorda Bay, Simms Bayou and Cibolo drainages (Hubbs et al., 1991; Nico et al., 2015). This suggests there is the potential for biotic resistance and competition in natural aquatic ecosystems to be utilized to minimize the impact and spread of H. cyanoguttatus in Louisiana, USA. Martinez et al. Lake Dunlap. Parental care of offspring exhibited by cichlid fishes greatly increases offspring survival rates. Texas Cichlid (Herichthys Cyanoguttatus) also known as the Rio Grande Cichlid is an aggressive freshwater fish native to the USA found mostly in the rivers of Texas (commonly in the Rio Grande) and northern Mexico.

It is used by San Antonio River Authority biologists as a biological indicator of unbalanced or stressed ecosystems (Gonzales and Moran, 2005). Itzkowitz M; Nyby J, 1982. God forgive me a sinner. They have been observed to spawn there in salinities as high as 8 psu (OT Lorenz, Georgia Southwestern State University, USA, personal communication, 2015). Blue Tilapia (Oreochromis aureus) now dominates Six Mile Creek near Tampa (OT Lorenz, Georgia Southwestern State University, USA, personal communication, 2015); First reported: 1940s, Recorded in heated power plant effluents in Powerton Lake near Pekin (Illinois River drainage), Tazewell County, after having been released accidentally. H. cyanoguttatus is a habitat generalist and will occupy lentic and lotic aquatic habitats including ponds, lagoons, creeks, rivers (in pools and backwaters) and springs with mixed substrate types (rocks, sand, mud, sand, clay, aquatic vegetation) (Robertson and Winemiller, 2003; Miller et al., 2005). Hubbs C, 1951. New Orleans, USA: University of New Orleans. A large number are also established in an isolated population in Port Sulphur, Plaquemines Parish, 50 miles southeast of New Orleans (OT Lorenz, Georgia Southwestern State University, USA, personal communication, 2015). Because sample sizes were very small for females, frequency comparison between sexes was not performed. Juvenile H. cyanoguttatus are pearly grey with white dots on the body and fins and two characteristic black spots on the centre of the body and the caudal fin base (Berg, 2010). Pair formation occurs before territory establishment and pairs will actively defend their territory to defend the eggs and fry. Lee DS; Gilbert CR; Hocutt CH; Jenkins RE; McAllister DE; Stauffer JRJr, 1980. Similarly, Lorenz (2008) cited anecdotal evidence of the decline of Gambusia affinis, Poecilia latipinna and Heterandria formosa in areas of Louisiana where H. cyanoguttatus has become well established. Kullander SO, 1983. Lorenz and O'Connell (2008) found reduced growth of H. cyanoguttatus in the presence of Lepomis macrochirus (bluegill). compared to the closely related monogamous Rio Grande cichlid, H. cyanoguttatus, males of H. minck-leyi were present at their nests less often and performed lower rates of aggressive offspring defense, and females compensated for the absence of their mates by performing higher levels of offspring defense. The liver and a small piece of ventral skeletal muscle American Midland Naturalist, 108(2):364-368. Publications of the Institute of Marine Science, 8:299-365. Nematodes of freshwater fishes of the Neotropical Region, 464 pp. Adults are dusky to olive above with 4-6 dark blotches (1st blotch most prominent) along the rear half of the body and a black blotch on caudal fin base. Cichlids exhibit a wide range of body shapes. Mills and Vevers (1989) report a diet of worms, crustaceans, insects and plant matter. In Louisiana, USA, they are often eaten and are popular with fly fishermen (OT Lorenz, Georgia Southwestern State University, USA, personal communication, 2015). Breeding males have a prominent nuchal hump (Page and Burr, 1991), and males are typically larger than females (Itzkowitz and Nyby, 1982). The size of individuals varies by species and ranges from about one inch (2.5 cm) to three feet (1 m). New Jersey, USA: Tetra Press, 208 pp. Kullander SO, 2003. Lorenz (2008) reported that salinities up to 16 ppt had no significant effect on the growth of H. cyanoguttatus. The name 'green Texas cichlid' often refers to H. carpintis; a species that is native to Mexico (Berg, 2010). USA: TFH Publications Inc. Courtenay WR Jr; Deacon JE, 1983. > 10°C, Cold average temp. In an artificial aquarium environment, Fontaine (1938) observed spawning of the species and noted that the female would swim over the cleaned nest and expel 1-5 eggs at a time followed by the male. http://www.fishbase.org. Lorenz (2008) found that it was often the most common species in urban canals in the New Orleans metropolitan area. (USGS nonindigenous aquatic species database)., Florida, USA: US Geological Survey.

There are iridescent blue-green spots or wavy lines on head, body and fins. Martinez VMV; Macedo MLA; Scholz T; Solis DG; Franco EFM, 2002. www.fishesoftexas.org. H. cyanoguttatus has been collected in small numbers from locations in Arizona, Illinois, Nevada, Ohio and Nebraska though the species is not considered to be established in these US states (Nico et al., 2015). Courtenay W R Jr, Deacon J E, 1983. Fishes of Texas Project and Online Database. Of particular note is the aggressive behaviour of the species as territories are established on the substrate and defended against all intruders. This cichlid is known for its cream and turquoise spots. It is this body shape from which their common name, "discus", is derived. Salgado-Maldonado et al. Seriously Fish (2015) states that eggs hatch in 2-3 days and the parents immediately move the fry to a pre-excavated pit in the substrate where the fry remain until the yolk sac is absorbed. (1974) and the personal observations of Lorenz (2008) support the proposition that H. cyanoguttatus competes with L. macrochirus for breeding sites in Florida and Louisiana, respectively. The fry will become free swimming in 4-5 days. Minimum temperature tolerances for fishes of the genera Signalosa and Herichthys in Texas. There are reports that H. cyanoguttatus may have been accidentally introduced from resident ornamental fish farms in Hillsborough County, Florida, USA, in the 1940s and 1950s due to flooding (Courtenay and Hensley, 1979; Conkel, 1993). Lorenz (2008) confirmed that H. cyanoguttatus will occur in elevated salinities in estuarine conditions in Lake Pontchartrain in New Orleans. Body oval, moderately compressed; large fish with a bulbous hump over the eyes; 1 pair of nostrils; mouth short, oblique, horizontal or slightly down pointing; jaws about equal or upper projecting; top jaw highly protrusible; jaw teeth mostly conical, but central teeth of outer series compressed and spatula-like in adult, closely … Adult males may also develop a pronounced "hump" on the head which is not present in tilapia. North America: originally restricted to the lower Rio Grande drainage in Texas, USA and south to northeastern Mexico. Cichlidae (Cichlids). 36377). Texas Cichlid (Rio Grande Cichlid) I'm just curious if anyone has heard of these fish, or owned any, and if they are still seen in the hobby, how rare are they, etc.. Before taking a 25 year break from the hobby, I had a pair of these from a fish store in Texas. It can grow over 33 centimeters in length, and males can develop a protrusion known as a nuchal hump on their head.
