I have been reading this thread for a couple of days now. (Not a lot of time during the day.) I was, am, are in simply amazement. I love your tank. I think if i were to try something like that i would start with a 10g.
Any signs of leaking, bowing? i guess you really couldn't see the back of the tank. What about you drain off? or do you just use your python. Your updated pics didn't show any plants, what happened to them? I really love your tank please keep up the good work and keep us updated. I have bookmarked Loaches r cool's thread and i am adding yours to update myself on all the happenings. Thanks for the inspiration. Mr. H
