Morichal de Morganito, Venezuela

Venezuela, Bolivarian Republic of, Amazonas

We did a colossal work assembling the biotope almost to scale of the reflected area. But in order to understand this biotope well it is necessary to explain its characteristics: What is a Morichal?

Morichales get their name from the Moriche Palm (Mauritia flexuosa) which is a palm which only grows and thrives where its roots can be underwater. Morichales is just the name given in Spanish to a large group of Moriche Palms.

As Morichales usually get their water from underground water springs, they maintain the crystal clear water all year round. They are places teeming with life where we find one of the highest concentrations of animal and plant species.

It is very difficult to find small or medium size rocks; rather, its rocks are the size of a football field. It is an environment comparable to the oasis in the desert where you only see sand and suddenly you come across of a wooden area full of water and life but in this case you will see plains of tall grass and suddenly find this tropical forests full of palm, trees and marsh plants.

The place where they are located is so flat that if you had an eagle’s eye view you could cross from Colombia to Venezuela. These springs, the Morichales, are the arteries that carry their waters to the main channel, the colossal Orinoco River and serve as habitat for small fish such as tetras and Apistogramma, where large predators feed and where their small fry grow to maturity.

This is one of the places where we can find huge underwater diversity and because of its unique characteristics we can study and photograph.

Aquarium decoration

The material used in this aquarium is not collected from its natural habitat, but it simulates the materials that we find in situ. Fruit tree wood as smooth as possible simulating the Tabebuia rosea tree and seeds of Lecythis pisonis. Besides leaves of great resemblance as it is the Magnolio. The aquarium lacks rock, since in this area we only find organic matter and silica sand of different granulometry.

Comment by the expert

Roberto Reis: Beautiful aquarium, based on photos and videos. Photos and videos of the fishes, even some spawning in the aquairum. Detailed description of equipments and water parameters.

Francesco Denitto: The natural biotope was excellently represented in aquarium. The reproduction looks extremely realistic. The owner has taken care of all details. Fauna, flora and decoration are well harmonised. A pity the lack of a video of the aquarium.

Donald C. Taphorn: The decorations immediately bring to mind the wild habitat, and the condition beauty and variety of the fishes makes this tank really top.
