Looks good, In my opinion if your going to have a schooling fish you shoulf have a lot of them. In my 55 I have around 30 tetras (red eye, serpae and black neon.) they all school together for the most part or break into 2-4 smaller groups but they are always funn to watch. I like having as many of one kind of fish as possible. Just plain fun to watch. Also 55 gives a lot of room for some neat aquascaping.

I changed the substrate to sand. Mostly because I was worried about the corys. They love it and it's fun to watch them play in the sand. My plants seem happier also.
