Mexico, Hidalgo, Coacuilco

This aquarium was inspired by the biotope of the Coacuilco River, which is located in the state of Hidalgo, Mexico. I tried to emulate the main parts of the river by using the rounded river rocks, and some fast flowing filter so the fish can swim againts the current.

I only use one type of fish wich is Xiphophorus birchmanni, because I consider that it is the most endangered species in that enviroment. So there is an urge and neccesity to show to the people this beatufil poecilid so everybody can breed them and consider the possibility of keeping them in the hobby and slow the pressure in its habitat.

Comment by the expert

Juan Miguel Artigas Azas: The aquarium is appealing and as close to nature as it could be. One valuable aspect in contrast to other aquariums I have examined in this contest is that the choosing of a species only aquarium for an endangered species is valuable, and likely to be maintained long term.

Jairo Arroyave: The main issue I found with this BAM was that, despite being a relatively simple biotope, its accurate recreation failed by not including most of the fish species, and other details such as the algae present on the surface of the pebbles and rocks. Notwithstanding these observations, the BIN is an aesthetically pleasing and balanced piece that conveys peace and allows contemplation of the beautiful poeciliid fish species Xiphophorus birchmanni.
