I am going to set up a planted freshwater tank; I am particular about biotopes as I like themes including the water, plants, hardscape and the fish.

The tank is a 150gal 60x24x24 and I can do with or without sump (I am leaning towards sump/wet-dry for top off and equipment and oxegenation).

I am very open but some of my thoughts are:

-probably not a blackwater tank as they are dim and my wife will probably not like that

-open to any area of the world as long as livestock is not too expensive or difficult to get

-probably not a fast moving water biotope

-have considered angelfish (probably should be blackwater), discus, African bushfish, gouramis.

are there other interesting fish that could be an interesting 'main' fish? other ideas?

Thx all!
