I have a baby Silver Aro of about 3 to 4 inches long and I want to get a solid plan out and begin stockpiling materials and gradually building to move him in when he grows more on me. I have plenty of space in the basement and I am thinking of doing it plywood and acrylic. Looking at my basement and thinking of arowana sizes and the potential for tankmates, I want to do dimensions of 96x40x30 to 120x40x36. Is the plywood a good idea or should I go 100% acrylic? I will also be building my own stand. I would appreciate any tips or material suggestions, I'm looking to learn and do it right the first time which is why I'm here.
