I know a lot of rocks contain minerals harmful for axies, but specifically which ones?
I bought a couple of rocks from the pet store. I have:
- Obsidian which should be fine
- Some kind of red and white porous rock ( http://www.petco.com/product/112310...e.aspx?CoreCat=LN_Shopping_FishSupplies_Decor )
- Something similar but just red
- Some kind of marble or white onyx (I think...)
The marble/onyx(?) concerns me because its chalky. Its definitely not as smooth as the obsidian.
