Hello! My room is full of animals, lol. I am trying to make more room for my hamster by moving my betta's 10 gallon tank from a random piece of Ikea furniture to the top of a 4 cube storage thing in my room. The thing is, the cube storage thing says the top part (which is where the tank would go) holds a max of 100 lbs according to the instruction booklet. My betta's tank has probably 9 gallons of water plus 10 lbs of sand. Would this be safe to put on top of the cube storage?
