I really like the look of a long tank. I know a taller tank would be more ideal for a WTF, but I already have too many things going for this project to flip it. I'm a little worried about space too, because anything that's going to be able to hold up to these guys is probably going to get large....

I'll look into those plants. Thanks! Tomorrow I'm hoping I can get to my local pet store and buy some wood to get started on the background/water feature.
