Goodeidae JORDAN, 1923. Subfamily:
Goodeinae JORDAN, 1923. Original description:
JORDAN, D. S. & GILBERT, C. H. (1882): Catalogue of the fishes collected by Mr. John Xantus at Cape San Lucas, which are now in the US Nat. Mus., with descriptions of eight new species. Proc. US Nat. Mus., 5: pp. 353-371 Origin of the species name:
the name furcidens (lat). refers to the forked teeth of the fish Type locality:
Not clear, JORDAN and GILBERT declare Cape San Lucas. HUBBS (1932) apparently recognizes the mistake and announces Colima as natural habitat. Meristic properties:
Dorsal fin = 14-17 rays;
ventral fin = 6 rays;
Pectoral fin = 14-16 rays.
Ilyodon furcidens originates from rivers and ponds in the Mexican federal states Colima and Jalisco. These Goodeids are normally found in quickly-flowing waters which drain the southern slopes of the Mesa Central into the Pacific. The males and females reach a body-size of about 10 cm. The culture of this species is easy. Aquariums of 80 liters or larger should be used. The water temperature should fluctuate between 18 °C and 26 °C. Hard water with a pH value of approximately 7 to 9 is best for these fish. Ilyodon furcidens is a peaceful fish and can be kept in a community tank. The males will often fight among themselves without injuring each other so hiding places in the aquarium, such as plants, stone constructions and roots will be beneficial. It is also advantageous to have several males in one tank, so that a possible, but rare conflict is spread over several fish. Ilyodon furcidens is a lively, strong swimming fish that will enjoy a water current in the aquarium. The fish develop a small cervical hump with increasing age. The food demands of Ilyodon furcidens are modest, so that flakes, frozen and live-food of all kinds are accepted. A vegetable portion should be included in the diet. Any algae in the aquarium will become an additional source of food. In its natural environment Ilyodon furcidens lives in many different biotopes, all with a dense growth of algae. Breeding succeeds without any assistance. After a pregnancy of about 7-8 weeks around 20 fry are delivered and these fry can be as much as 15-20 mms long. This large size means raising the fry is without trouble. When Ilyodon furcidens is kept in a species tank, the younger generations increase naturally, since the older animals do not chase their young. The highest number of offspring in one spawn that I know was 54!
