The Allotoca from "Laguna de
Zacapu" is described
by KEES DE JONG
Some species are already kept for a while by
aquarists before getting their scientific name. This is also the case with
the Allotoca-species which is to be found in the Zacapu Lake.
Allotoca zacapuensis became known under the name
"Allotoca spec. Zacapu " and also under the English name"
Allotoca spec. Hummel ".
Allotoca zacapuensis clearly differs from the
other species of the genus Allotoca and this was the reason for Meyer,
Radda and Dominguez (2001) to give this species its own (scientific) name.
In their article published in 2001 they called
this species after its area of distribution: "Allotoca zacapuensis".
Except the sex organ typical for male Goodeids
there are no further differences between the males and females.
Corresponding to the original description
Allotoca zacapuensis reaches a size of approximately 3 centimetres.
Although it is none of the larger species within the genus Allotoca, they
nevertheless can become a few centimetres larger in my opinion.
In the year 2000 I had the opportunity to catch
Allotoca zacapuensis in the Zacapu Lake.
I have caught only 10 specimen of the Zacapu
Allotoca altogether. I accommodated these fish in the laboratory (Aqua
lab) of the university of Morelia. Two pairs of them I took home with me
in the end.
For quite a while there were no problems with
Allotoca zacapuensis. But when the temperature rose during the summer, the
fish got an infection and large spots appeared on their bodies. Some fish
died of the infection. At a lower temperatures the fish were doing better
again so that I could keep a number of Allotoca zacapuensis alive.
