How to Set Up A Colombian Biotope Aquarium
I have been milling over the idea of creating a Colombian River biotope in my
53GAL tank. I have the fish species (Emperor Tetra, Otocinclus affinis,
Peckoltia pulcher and Skunk Corydoras) and some of the water params but I am
at a loss for;
1) Aquatic Plants (what are they?)
2) River type (fast flowing, slow, moderate)
3) River biotope (does it flood rain forest?, does it dry up on occassion?)
I have noticed that your site seems to have volumes of information on Brazil
and other South American countries. Any leads or information would be
appreciated.
It really depends on what specific part of Colombia you're looking to recreate.
I've never been to Colombia so I can't give you specific details, though there
are rivers in some regions that flood while in others they may run dry during
some parts of the year. You're going to find rivers that run the gamut from
fast-flowing to being virtually still -- it really depends on what you want to
create.
It also depends how picky you want to be about your biotope because technically,
the fish you name aren't found in the same waters:
Emperor Tetra: Rio San Juan and the Rio Atrata of the watershed of Western
Columbia
Corydoras arcuatus: Ecuador, Rio Napo River system; Peru, Rio Yavari and the Rio
Pacaya.
Peckoltia pulcher: South America; sections of the Rio Negro near Moura (Brazil).
Otocinclus affinis: South America; rivers with heavy vegetation is the Rio de
Janeiro area (Brazil).

Overfishing may hurt Amazon forest trees
(2/5/2008) Overfishing is reducing the effectiveness of seed dispersal by fish in the Brazilian Pantanal, reports Nature. The research suggests that fishing practices can affect forest health.

Piranhas originated when Amazon was flooded by seawater
(12/4/2007) South America's piranha family of fish -- notorious as eaters of flesh -- can be traced back to a single ancestor which dispersed when the Amazon was flooded by seawater some five million years ago, report researchers from the Institut de Recherche Pour le Developpement (IRD). Today piranhas are exclusively freshwater fish found from the Orinoco River basin in Venezuela to the Parana in Argentina.
How to save the world's oceans from overfishing
(7/8/2007) Global fishing stocks are in trouble. After expanding from 18 millions tons in 1950 to around 94 million tons in 2000, annual world fish catch has leveled off and may even be declining. Scientists estimate that the number of large predatory fish in the oceans has fallen by 90 percent since the 1950s, while about one-quarter of the world's fisheries are overexploited, depleted, or recovering from depletion. Despite these dire trends, the situation is changing. Today some of the world's largest environmental groups are focused on addressing the health of marine life and oceans, while sustainable fisheries management is at the top of the agenda for intergovenmental bodies. At the forefront of these efforts is Mike Sutton, director of the Monterey Bay Aquarium's conservation program: the Center for the Future of the Oceans. The aquarium, which has long been recognized as one of the world's most important marine research facilities, is pioneering new strategies for protecting the planet's oceans. Sutton says the approach has four parts: establishing new marine protected areas, pushing for ocean policy reform, promoting sustainable seafood, and protecting wildlife and marine ecosystems.
