I just recently setup a 4 gallon tank, but the only hardscape i have in it is one piece of mopani wood that i purchased from Petco. I went to some other LFS and couldn't find any wood or rocks small enough for a 4 gallon tank. I was wondering if anyone here knew of a place online that would sell hardscape materials that would be small enough for a 4 gallon? Or if anyone had any they aren't using and are willing to sell? Thanks.
