I returned my danios at my LFS looking to get another Gourami suitable for a Ten Gallon. I was unaware Blue gouramis were the same species as Gold Gouramis. The store had the golden gouramis listed 10 gallon min and 4" maximum length. Now I have done the research yikes! Am I able to keep the fish in a 10 gallon successfully? Its about 2 inches now.
