I totally agree Acer; however, I went to a local store because I had a caulerpa problem in my tank. I was looking for a specific fish, the store didn't have it, and told me that a kole tang would do a great job controlling it. Although I didn't research the fish, I purchased it only to find out that it cannot consume that type of algae because of the anatomy of it's mouth. Ethics are a part of business also. Local stores complain about people purchasing items online instead of supporting them yet they repay us by giving "bad" advise. I have seen ethical issues at every local pet store which is how I found this forum. I would like to thank everyone here for their contributions. We are on here because we want to advance this hobby not earn a living.
