Man, this is going to be a cool build!!!
I wish we had basements here in Texas, as it would be my Fish Room for sure!!! But considering we only have about 1' of topsoil till you start hitting the solid limestone bedrock, a basement would be a major demo job!!!
Anyway I agree about seeing 2 sides of the tank! A buddy of mine had a 180g in wall, and while it was cool, I didn't care for only seeing the front! I think Your Idea will be perfect! Subscribed!!! Also you r fish choice is VERY COOL!!!
Keep up the great work!
