i would love to turn my 10 gallon tank into an asian theme tank. it doesnt have any fish in it so now is the time to change it up a bit. i would like to have some kind of bamboo and either driftwood or some kind of rock cave. does anyone have an asian theme tank? can you post pics? i need some ideas lol.. also can i put regular rocks from outside into a freshwater tank or do they have to be store bought??
