Aquarium information

Aquarium description

Set-up date
July 2020
Aquarium decoration

This aquarium is setup for of 3 Vieja fenestrata, 6 Poecilia mexicana, 10 Astyanax mexicanus and Eleotris pisonis, as well as containing the two main aquatic plants that are Cabomba palaeformis and Ceratophyllum demersum. Some leaves on the beige substrate, the rocks and the trunks with calcareous sediments.

Aquarium equipment

Sunny 600 cascade filter with sponge filtering loads and cannulas.
The light it has is based on led.

Fish care

The fish that live in the biotope need shelters and abundant vegetation which was placed in the aquarium for a better condition for the fish.

Fishes:

  • Vieja fenestrata 3
  • Poecilia mexicana 6
  • Astyanax mexicanus 10
  • Gobiomorus dormitor 1
Plant care

The two plants Cabomba palaeformis and Ceratophyllum demersum with their dense foliage provide refuges for the fish that live there, especially the fingerlings of the Poecilidae.

Plants:

  • Cabomba palaeformis 20
  • Ceratophyllum demersum 3
Water care

Regarding the temperature and pH, I do not have much problem in controlling since in the area the water is alkaline and hard, the same in terms of temperature I am in a hot area.

Comment by the expert

Juan Miguel Artigas Azas: The aquarium is very appealing and as close to nature as it could be, really beautifully made. There is however not a very detail description on how to replicate it. It is beautifully made. Nonetheless, the main problem I see with this aquarium is that it is not sustainable, since the aquarium is very small for the chosen balance of species. Vieja fenestrata (an exotic in the river) will soon outgrow the aquarium and in a very short time eat all the vegetation. The one Gobiomorus dormitor will definitely eat the Astyanax mexicanus and Poecilia mexicana. In my opinion a much substainable selection of species for this beautiful aquarium would have been Poecilia mexicana and Xiphophorus variatus, with one selection of the crustaceans inhabiting the river.

Jairo Arroyave: BAM is a very good representation of the BIN, including approximately half of the fish diversity in nature, and a number of plant species. Biotic and and abiotic elements coexist in a balanced fashion. Information offered to recreate the BAM appears adequate and sufficient.
