Rio Cenepa Pencilfish, Apistogramma Cacatuoides, Otocinculus Catfish
Eleocharis montevidensis
No fertizilation
This biotope was constructed to mimic a shallow drainage area in the Río Cenepa, river located in Peru which also runs along the Ecuadorian border. Although its geographical location has created its fair share of disputes, it boasts a widely diverse variety of fish and animals which inhabit it. Shallow areas within the river rise significantly during heavy storms, accumulating large amounts of leaf litter and falling fruits due to high winds. When storms subside, small fish find their way to these areas and create their own environments within. Adding small amounts of Peruvian botanicals bi-weekly has allowed for a beautiful display of the process of leaves and fruit pods decaying underwater. Small frequent water changes along with a lack of disturbance to the substrate has allowed the tank to develop, decay, and create a stormy looking environment full of nooks and crannies for the tanks inhabitants to explore. It is a pleasure to witness the natural behaviors and the effects of providing a space built so intentionally for the fish that reside in it. https://iwgia.org/images/publications/a_chronicle_of_deception.pdf https://mapcarta.com/19742884
Nice biotope aquarium, just wished you would have more accurately identified the fishes living in it.
The dark, moody vibe of this display is dramatic, and highly suggestive of the shaded forest streams it is attempting to replicate. I like the organic vibe, the detritus, the algae, the dense of decay over which the fishes forage. Combined with subdued but natural planting, this works very well. The way the display fades into darkness towards the back of the tank is also very effective. The fish appear to be in good condition, however, for me the display loses some points due to the slightly small nature of the tank. Apistogramma cacatuoides can be aggressive, even towards their partners and it feels there might not be many places for a bullied individual to get away or hide in this display. Aside from this, I think it is very well-constructed biotope.
