That tank looks awesome!!!! What a community that looks to be, too. The ornate is the one that really stood out for me. And thanks for the info on the substrate, that gives me some ideas dor a tank I've got standing empty right now. And kudos on the wood!
believe it or not the wood was FREE. i just went exploring a local dry creek and found this nice 9 foot section. i cut it into 4 parts. here is what it looked like before the cuts.
