Not really.
Biotope's are such a vast and varied thing.
Some biotopes will be no more than a still puddle. I believe there is a biotope that can be achieved within everyone's means or budget.
A little research can lead to something realistic and achievable.
Ah yes of course. A puddle biotope would be, without a doubt, a grand display. Stock could be some giardia and mosqito larvae.

Some of my favorite species to keep, have been rheophillic cichlid species of Central America. My problem has always been getting enough flow, to hold aggression down, even with pumps of over 2000 GPH aimed into a tank.

Here are some photos of a stream in Panama, that might be an example.



Usually the only aquatic plants are algae, although plenty of overhanging terrestrial vegetation.
But even the slower flowing rivers I visited, (although serious flow compared to most aquariums), were generally poorly forested below the surface.

As I have been experimenting with and researching more on rheophilic aquatics, I have come to realize the flow rate and movement of water people "expect" to see is highly underrated.
This is reversed when it comes to aquatic vegetation. We give a very "peak" ecosystem for a few niche areas when styling tanks with plants. Even the natural ones. Nothing wrong with it but I don't think people are aware of how little vegetation is purely submerged. Most is emergent or riparian.

In a 75gal African stream tank I did. I housed 10 male pelvicachromis kribensis with a single female. Due to the flow and keeping fish busy with grazing on algae and plants there was almost no aggression.

I currently have almost 16,000L/h running on a 75gal stream tank and the fish still sometimes spend time swimming directly in the outflow section of the tank. They are rheophilic species so swimming in currents is second nature to them.

I feel, water movement, and more importantly, increased water movement can help a lot of tanks. I do not mean washing machine vortexes. I am talking about thought out water flow plans for the tank using powerheads/circulation pumps etc., as well as decor and tank walls to make a proper "flow habitat". This helps spread food, nutrients, oxygen and helps in many other ways.
