    I'm looking into which substrate i want to get for my tank and i have a question. Ive heard that you want a fairly fine substrate so there is no chance of a sharp bit hurting the octopus. So i was curious. Anyone have any experience or opinions about a fine volcanic substrate?

    I've never encountered anyone using fine volcanic substrate. Aragonite sand has the advantag of helping keep the pH stable, and that's what we've been recommending.

    Aside from the pH benefit. I was just curious as to the possibility of the volcanic sand harming the octopus?
