The BIOTOPE AQUARIUM Project 

Most aquarists start their journey in fishkeeping by simply mixing random animals into an aquarium and decorating the aquarium to suit their personal aesthetics.  As we learn more, some of us endeavor to recreate natural habitats instead of mish-mash communities of species from different parts of the world because there is a special appeal watching animals interact with their environments as nature intended … saying nothing of creating healthier natural environments for fishes.
