Suggestions for 30

I have a black background on my other two tanks and for the most part I like that look but I have seen some really nice tanks with the picture type background too. I still don't know what kind of background we will do.
 
A black background on all sides except the front will be nice.:)

That would be nice, but IMHO I think it would be better to just have it on the back b/c you can see the fish/decor from more sides.

Especially when you can't find a particular fish and you go crazy looking for it.
 
Some driftwood to give some vertical appeal.

I had a piece of driftwood in the 20 and even after soaking it leaked tannins giving the aquarium a murky appearance. I have a resin cave that we painted black with Krylon Fusion. I hope to post pictures soon.
