my tarantula (medium size rose hair ) was in a ten gallon tank with a hide, water dish, and fake desert plant, but today i moved it into the adult terrestrial tarantula cage from www.tarantulacages.com..... the cage is a little smaller, rite now it just has a hide in there, i didnt put the water dish and fake desert plant back in becuase i wanted the tarantula to have room to walk around and dig.....but is my tarantula going to dehydrate with out the water dish ????? i think it comes from the desert but im not sure, i have the tarantula keepers guide book but i didnt get that far into reading it yet..... when the water dish was in there the tarantula would just dig and fill it with dirt, thats what is going to happen if i put it back in there becuase the cage is a little smaller, or should i put the water dish in anyway ????
