I seem to hear this type of thing on every forum I have looked at..." Its the Wrong type of Substrate" .."You would never see those fish in the Wild together"...etc,etc,etc. Just because you or the way you keep a tank, your house, your animals are the same as anyone else does not make it WRONG!
This is a Hobby. for the most part we enjoy looking and keeping fish it does not matter if your "BIOTOBE" includes a Pineapple under the sea from Spongebob or a Sunken Ship with bubbles coming out of it. What matters if that you/we respect the animals we keep by giving them a good safe, clean place to live and understand what they NEED.
I have not posted the final few pictures yet with the Rocks and open swimming areas yet Or the filtration set up I have used. I plan on getting to that later in the week.
