Speaking of artificial and natural habitat is nothing but romantic. The only
point is whether the species reproduces and stays healthy or not. Most
species don4t need a copy of their natural habitat but certain triggers to
feel comfortable. A slamander e.g. doesn4t care whether he hides under a
rock, a wood or a plant-pot (made from clay or plastic). He just wants
shelter and darkness. Otherwise there wouldn4t be so many reproduction
successes of so many species - over many generations. Elefants don4t need
the Serengeti. Tigers don4t need the jungle, neons don4t need the Amazone.
But they need proper conditions.

And the fish mostly don4t care for this rubbish in the tanks. Anyway to me
this type of decoration hurts my eyes.
And I can show you biotopes in SA and Afrika which to transfer to captive
maintenance would rise protests from all directions. But the fish like it
and are very abundant there.
