New Guinea River

By Rhett Butler


A biotope aquaria is an aquarium that is set-up to simulate a natural habitat. The fish, plants, water chemistry, and furnishings are similar to those that can be found in a specific natural setting.

Always check compatibility! Some species from a particular habitat are not suitable tankmates. For example, the Peacock Bass will eat small tetras since they are their natural food in the wild.

The biotope aquarium can be adapted by adding species from disparate areas that have similar water requirements.
