Please try not to flame me too much but I am considering a yellow tang for my 55. I have read on this site and others that a 75 or larger is recommended but I am trying to find out why. I went to the lfs and measured up to a 120 and each one was 48" long just like my 55. So my question is why do I need a larger tank if the whole purpose was for swimming? Its the same distance no matter which tank I have. I realize that the bigger ones are deeper but is that really going to make that much of a difference? Thanks in advance for ALL honest advice. Just please be gentle as I am new to this.
