The flora/fauna of a distinct biotope, and their mutual compatibility will depend on the exact conditions of the biotope in question including type of habitat and parameters of water. For example, we could take Lake Victoria in Africa as an example of a biotope or the Amazon river. The conditions in both differ widely, and the creatures from one will not survive in the other. Similarly the marine coral reef biotope is different. Our basic unique expertise lies in authentic recreation of such biotopes.
