I figure pond owners would probably know the answer to this question or would have the best advice, i have a 20 gallon and i like the oriental theme i see in in big asian restaurant goldfish tanks, i need guide lines on how to do this since i notice that pond owners kinda flow in the direction of that aquascapeing style with the pebbles and what not, i would use sparkly gravel ( seems to be black and silver) or natrual or white or red gravel, want my aquarium to have that oriental feel to it i often see in the asian restuarant tanks and in ponds. thank you in advance
