Wow, thanks, man.that may be the single most beautiful "normal" * fishtank I have ever seen. If there were a Nobel Prize in Aquarium Arts that would be a strong contender.
*as opposed to, say, ADA contest tanks. Which are downright breathtaking, but are works of art designed to last in their perfection only long enough for a picture to be taken. And intended to look more like terrestrial landscapes than actual places where fish might, um, live.
