Ok so the last octo I kept was in a fairly empty tank just some shells ect nothing on the bottom of the tank. What kind of sand should I be using? I know coral gravel is far too course for there senstive skin. I was thinking sugar sand would be a good option. Is this to sharp? Is there a good grit to feel ie rubbing it between my fingers? The other problem is that my tank return is through the bottom in an reverse under gravel filter set up. I want to enshure that it is not going to be too restrictive of the flow. Any thoughts on aquascapeing? I have a tall 130 gallon tank for a not so large octo.
