When these little guys pair off, I will be building a new stand. This one will stack 3-4 tanks. The tanks will be 30 gallon breeder tanks. I'm trying to make use of the little room I have here. Currently living in a studio about the size of a small 2 car garage. I have a bed, table, keyboard(I teach piano), tv, bathroom, closet(not built-in). So, it does get pretty cramped really quickly. I don't understand why they don't have built-in closets in Taiwan. It would save room.
