I have a 40g cube tank and was wondering if it is a terrible idea to add a baby tang into my tank once its ready. The tank has been running for about 8 weeks now and I have slowly been building the tank up and planning on adding a baby tang in the future, but was just wondering what others think. I know that any tang will out grow the tank and I am more than understanding of the fact that I would have to bring it back to the fish store I work at.
