I mistakenly bought play sand, thinking there would be no pebbles or anything in it. However I was wrong. I currently am looking at different sands. So far this is the one I am most attracted to. I just want to know if it is safe for frogs or freshwater fish.

CaribSea Instant Aquarium Moonlight Sand Gravel at PETCO

This is another option I was looking at, but it seems it is more for salt water aquariums. Unless the sand does not truly matter with freshwater vs marine.
