Laguna El Arco, Ocoyoacac, Mexico

Sponsored by

Mexico, State of Mexico, Ocoyoacac

This biotope aquarium represents the marginal area of ​​Laguna el Arco, La Marquesa National Park, where you can find a population of goodeid Girardinichthys multiradiatus, locally known as Mexclapique, a fish endemic to Mexico with the category of endangered species. according to the IUCN, while in NOM-059-SEMARNAT-2010 this species is not considered at risk.

For the recreation of this biotope aquarium, the Mexcalpique and the Acocil are used as the main inhabitants. The behavior within the aquarium is peaceful and the number of specimens chosen from both species does not represent any problem of aggressiveness between themselves. The choice was limited to these species since they are endemic to the area and represent the richness of endemisms that exist in central Mexico, in addition we contribute in some way to their conservation. As for flora, other plants present in the BIN are not used since what is recreated is the submerged part where Elodea predominates in 98% of the Laguna.

All elements used in the aquarium (plants, roots and substrate) were collected responsibly directly from the BIN.

Aquarium equipment

Filtration: 650 L/H internal filter Aqua-Krill.

Lighting: 3 white light fluorescent bulbs, each 8W and 6500ºK. The aquarium is influenced by sunlight for 2.5H and a photoperiod of artificial light of 6H.

Fishlist:

  • Girardinichthys multiradiatus (Goodeidae)

Crustacean:

  • Cambarellus montezumae (Cambaridae)

Fish care

Regarding the care of the fish, they are fed 2 times a day, in the mornings with “TetraPro tropical crisps” food and in the afternoons with “TetraColor tropical granules”, additionally 3 times a week they are provided with live food (water flea, Daphnia sp.). The acociles (Cambarellus montezumae) are provided with balanced food “El Pedregal” once a day.

Plant care

The plants have low requirements, so they do not require special care, with the photoperiod provided they grow quite healthy. The most damaged parts are pruned weekly.

Water care

Every weekend, deep maintenance is carried out on the aquarium (cleaning the filter, glass, siphoning the bottom, pruning the most damaged parts of the plants and a 25% water change).

Comment by the expert

Michael Köck: The biotope shows the typical situation within the dense Egeria fields, which is biotope adequat. For giving the aquarium a bit more excitement at an already high level, it would have been a possibility to show a minor part of the aquarium unplanted, but this is just a comment from my subjective perspective and doesn’t effect the quality of the biotope aquarium. Overall statement: Very well done!

Jairo Arroyave: The BAM is beautiful and it is seemingly a fair representation of the BIN, although BIN underwater footage and video were absent. The complexity of the habitat is moderate and the participant made a very good job at portraying with different inhabitants in good balance and nice aesthetics. I realy liked this BAM!
