what kind of environment are you trying to create in your aquarium?

[SuperDuperMan]

like amazon basin, mangrove swamp, great barrier reef, etc?

1 tank is strictly "rocky Central American stream with snags",another is "South American sunken log and gravel bar",another is "sunken tree root" (takes up half the tank volume),another is "North American Gravel stream bed" ( turns over at 30X tank volume hourly... for my Darters)

Bright, blue and green, and tropical feel, yet natural.

I only keep freshwater fish so I go with the tropical environment. Amazon sword plants, other tall plants, sand substrate with some rocks and driftwood.
