Currently I have the standard fish tank style gravel in mine but I am giong to remove it tomorrow when I clean the tank. I want something to cover the bottom and create a ledge on one side of the tank for them to lay on under the water, but...
What kind of rocks should I use?
Will any rock work as long as I wash them off really good?
Meaning, can I go to a Lowe's or other hardware store and buy a bag of large river rocks or the large white marble chip rocks to put in the tank?
Is there anything special about "traditional fish tank rocks/gravels"?
This is what I am looking at using. http://www.lowes.com/lowes/lkn?action=p ... lpage=none
