Here's a picture of my tank. It's still a little cloudy and there are a few more plants to come, but I think it's looking alright. And my cory cats love it!
I use to have sand but I couldn't stand the sight of waste floating around on top of the sand. That and it always mad a mess in my tank. but it looks good in your tank.
Nice tank. It looks like you have given your corys a wonderful new tank (new as far as they are concerned )
It might just be the picture, but it looks like you have somewhat of a thick layer of sand there. Just make sure those anaerobes don't make too much gas. Nice change from the gravel.
