Aquarium Advice Regular
I currently have of medium sized rocks and some smaller gravel, but as the food tends to bury itself in the rocks where my bottom feeders can't reach it, I think I need a much smaller sized substrate. I have a 30 gal with 1 betta, 3 white clouds, 2-3 otos, and 5 cories. As I really enjoy the cories and want to focus more on them, and have read that they prefer a sand substrate, I'd like to switch. So I did some research on how to safely swap out my current substrate and put a new one in. But what kind of sand should I get, and where can I get it, and how much will I need?
