If you had the choice

I think I would go with 5 - 1000gal. tanks so I could get some different setups going and keep things interesting. I would put one in each room so each room could represent a different biotope. South American, African, Southeast Asian, etc... Wouldn't that be great... :dance:
 
You could also decorate each room with its native art and decor
