INFORMATION ABOUT BIOTOPE

Description of the area surrounding the biotope: The Papaloapan river or Rio de las Mariposas (river of the butterflies) flows down to the east from the volcanic highlands of the Mexican plateau, originating from cold water springs in these mountains. At first a rapid mountain stream, further downstream the river becomes wider and flows peacefully across a landscape characterized by tropical lowland vegetation, eventually emptying into the Gulf of México at the city of Alvarado, between extremely beautiful salt lagoons. The drainage of the Papaloapan and its smaller tributaries is bordered to the north by a volcano belt 60 kilometers north of Veracruz, the state capital. This belt is the remains of a large volcanic chain that once extended from the central part of the country to the Gulf of México, and meets the sea at Punta del Morro, just south of the 20th parallel north. This mountain chain acts as an effective geographical barrier to the spread of freshwater fish.

Description of the underwater landscape of the biotope: A tank was created to replicate the natural habitat of Thorichthys maculipinnis. The aquarium was based in the Papaloapán River basin, Mexico. I used driftwoods branches and leaves from the Zapota tree as decor. All the rocks, small pebbles are all collected from the local river to make the Scape look as natural as possible.

This tank was ranked 126th in the International Biotope Aquarium Design Contest 2018.
