natural decor for BW tanks?

[BigB]

Hey everyone my GSP is growing faster then expected, his 20gal is coming to small for him. I expected it to happen, but it happened very fast. Luckily i am just about to get a new 125 to move my planted tank to. So I will have a free 30gal for him to play in in a few weeks.

My question is, what is some good natural looking decor? I heard talk of driftwood rotting in high brackish conditions which he will need. I plan to use a small layer of marine sand or pool sand and some large river rocks. But i can not think of anything natural looking that is tall enough to block line of sight. Seen some fake mongrove roots but they are $$$$.

Also what does the GSP natural habitat look like. Trying to recreate it as much as possible, guess he goes from mangrove to reef area? so lets keep him in the mangrove area cause well i am low on $$$ lol

Any ideas or pics of your tanks. And no fake plants I hate fake plants

Reef wouldn't really be natural, as far as I know they've never been collected that far out of the river mouth, they probably get washed out that far occasionally, but it's not design of the species. Live rock is actually a fair visual approximation of river mouths here on LI(looks is as far as I goes of course), but we're way less tropical than these guys are from.

I like the combination of sand, Ocean Rock and fake plants, oh and the obligitary algae that comes to make your nice white rock brown.
