hi sorry so late to respond, haven't been on site in a while. For driftwood for my aquariums I get it at an aquarium only store. I boil my wood for a few hours to get the tannins out as I don't want my aquariums to have tea colored water. I boil till the water is clear , changing it as needed , last batch I put a dash of Prime in, so if they start rasping on the wood right after I add it , they don't get the chlorine and chlorimides juice from the wood. Also, I think there is a site , may dr. fosters aquarium stuff you can order it from. Best chance to get the shape and height you want would be an aquarium only store. good luck , georgie oh, ps if you boil the wood , use an old pot the tannins will ruin it for ''people cooking''. I use my husband's lobster pot cuz I hated seeing him put live lobsters in it :whistle: so now I boil rocks, wood, anything going in the tank,I have this big pot now.:clap:
