Nice! I have a tsn in with my bass and am hoping to build one of these tanks in a year or two to accommodate him as he grows, that being said where are you located? A vendor on here snook 21 is who I get all my pbass from and I believe he ships internationally as well. Also always has great prices and a great guy to deal with. If I was doing an amazon theme tank though pbass would be my first thought, whatever route you choose congrats on an awesome build so far and looking forward to future progress.
I know this is mfk but I also have to admit I always thought a giant school of neon Tetras would look awesome in a giant tank so even if you go super small, I for one will still be stoked!
