Chapalichthys pardalis

ALVAREZ, 1963

Chapalichthys pardalis ALVAREZ, 1963
Chapalichthys peraticus ALVAREZ, 1963

English name:
Polka-dot splitfin

Family:
Goodeidae JORDAN, 1923.

Subfamily:
Goodeinae JORDAN, 1923.

Original description:
ALVAREZ, J. (1963): Ictiologia Michoac√°na. 3. Los peces de San Juanico y de Tocumbo; Mich. Ann. Esc. Nac. Cienc. Biol. 12 (1 - 4): pp. 111-138.

Derivation of the species name:
pardalis (Greek) = Panther (because of the pattern on the bodies of these fish).

Type locality:
Tocumbo, 40 km south of Lago de Chapala, Michoac√°n, Mexico.

Meristic properties:
Dorsal fin = 14-16 rays;
Anal fin = 14-16 rays;
 

Keeping Chapalichthys paradalis is not difficult. Aquariums of 100 litres or more are sufficient for a school of this lively species. The temperature should vary between 18 ¬įC and 22 ¬įC.

The males reach a size of approx. 6 cm, the females of approx. 8 cm. The colouring is olive-brown. A couple of greenish shimmering scales are distributed over the body. After having reached their full length, the animals develop broad backs.

In its natural habitat the fish probably predominantly eat live food. This has to be considered if one keeps these fish are kept in an aquarium. Nevertheless, they accept flakes without any problems.

Breeding is simple. However, one has to be aware of the fact that the older fish will go after their young. 15 to 20 (and in some cases even more) young of different sizes are released in one litter. If there are many young in one litter they are usually smaller; if there are only a few young in one litter they are usually larger.
