i am planning on building a fishroom. I can either build a dedicated structure or get a shipping container. Getting a metal shipping container will be a lot easier, but i do not have much room to move a 20' container. I was then thinking that i would get a 10' container. My only question is would it be big enough? I want to have a utility sink and at least 6 40 gallon breeders and a large tank, possibly a 150 tall. I am looking for input on this.
