I have to admit, I am really impressed with the textured painted tank 
I have gravel, sand and bare bottom at the moment. I don't like the looks of the bare bottom, but it's simply an isolation tank. I prefer the tank that has sand. Its easier to vacuum and looks good. I actually enjoy watching the fish play in the sand...picking up mouthfuls and spitting it out or causing swirls when they dart off. I do have way too much and wish I wouldn't have made it so deep. But, I keep stirring it during each water change.
(still liking the painted bottom!)
