Thanks Clare12345 and msnikkistar!
A Hill: Interesting point about the Java Fern - I'm not sure how to deal with this issue. I suppose I could try to tie it onto something, but that's definitely not the look I was wanting. It was actually planted in the tank at the LPS so I just assumed that I would be able to do the same in my tank. I'll have to think more about this I guess. As for the Amano Shrimp, I'll definitely keep their size in mind. I was intending to only start with 3 anyway and potentially work my way up to 6 once I got a better gauge of their size in the tank. Cherry Shrimp are definitely out for me though - from everything I've read they're much too easy to breed (a situation that I'm hoping to avoid by using Amano Shrimp).
