Allotoca goslinei SMITH & MILLER, 1987 English name:
Banded Allotoca Habitat:
Rio Potrero Grande, a tributary river of the Rio Ameca 10 kilometres west of the town of Ameca nearby the road to Atenguillo, Jalisco, Mexico. The species is distributed over larger areas of the Ameca basin. Allotoca goslinei has probably been imported to Europe by RADDA. As the English name “Banded Allotoca†coined by SMITH & MILLER indicates the species has got typical black spots that are fairly regular and look like vertical bands. Apart from that the colouring of the fish is rather plain but by no means unattractive. Allotoca goslinei reaches a size of only 6 centimetres but sexual maturity is usually reached at a size of 4 centimetres. A higher number of vertebra and rays in the dorsal and anal fins distinguishes Allotoca goslinei from other species of the genus. The males not only have an andropodium but also their dorsal fin begins closer to the front part of their bodies. In their natural habitat Allotoca goslinei have been found in shallow lakeside regions or shallow pools under plants; in a depth of about 15 to 30 centimetres. The water temperature in this part of the Mexican uplands rarely rises above 20 °C. Allotoca goslinei (Text by JAN DE MOREE, Netherlands, 2001) Probably, this is a seriously threatened species. At several places we were unable to find these fish. Only west of the town of Ameca, in the Rio Potrero Grande, we discovered a few specimens. At the end of the drought there was only a little water left, which was very cold. Allotoca goslinei is a greyish brown coloured, extended fish with – and this is its main characteristic – a black spot in the middle of its body. The species is omnivorous. Unfortunately, there is no further experience with Allotoca goslinei. |
