Alloophorus robustus HUBBS & TURNER, 1937 English name:
Bulldog Goodeid Family:
Goodeidae JORDAN, 1923 Subfamily:
Goodeinae JORDAN, 1923 Original description:
BEAN, T. H. (1892): Notes on Fishes Collected in Mexico by Professor Dugès, with Descriptions of New Species. Proc. U.S. Nat. Mus., 15: pp. 283 - 287. Derivation of the species name:
named robustus after the Latin word for strong, robust, stout Type locality:
Tributary of the Rio Tuxpan, 8 km north of Pihuamo, close to the affluence of the Rio Terrero, Jalisco, Mexico. Meristic properties:
Anal fin = 14 - 16 rays;
Pectoral fin = 16 - 17 rays;
Ventral fin = 6 rays; The genus-name is derived from Greek and refers to the ovary, which is different from other Goodeid genera. That difference is described in the work of HUBBS & TURNER (Studies of the fishes of the order Cyprinodontes, 1939), who came to the conclusion that Alloophorus is the most primitive genus within the family of Goodeids, although the fry are born with Trophotaenia (which is not the case with Ataeniobius toweri). The luxuriously planted aquarium for Allophorus robustus should be at least 100 centimetres long. Stone constructions with hiding-places are also advisable, because this species prefers to live secluded. The temperature should be between 16 °C and 22 °C. Alloophorus can be kept together with other fish as long as they are big enough not to be regarded as prey. When confronted with other fish Alloophorus shows no aggression. Smaller fish, earthworms, water fleas, mosquito larvae, all sorts of frozen food and flakes are willingly accepted. This species has reproduced in captivity several times. The number of fry varies between 20 and 50. Huge females with small litters may deliver fry that have a size of about 17 to 19 mm. Because of the size of the young, breeding is without problems. It is important to seperate the fry from their mother, otherwise they will be chased excessively. The highest number of young in a single litter is, as far as I know, 64. Big open waters are the habitat of this timid and huge species. The full-grown animals prefer a (strong) current and appear for instance in the Lago Orandino. The hunting behaviour of these fish is quite remarkable, since they stalk their prey (small fish, aquatic insects) like a pike. Alloophorus can be found in several habitats and so the species seems not to be endangered, at this point. Probably, this species is still common in all bigger waters.
