My .02$. It has been suggested to me that I could get a blue hippo tang for my 120 gallon and keep it for a couple years till it gets too big and then give it to the LFS or a friend. Also, people have told me on here that it could work, give it a shot. I have always wanted one. I think this is cruel. 1. Why get a fish that you know will outgrow your tank? It's like when people get a St Bernard puppy in a one bedroom apartment. It's wrong. 2, This hobby can be a strain on wild population I think because of this "give it a shot" mentality. Yes, it has worked sometimes but most of the time not. People have already "given it a shot" and we should be responsible about this hobby and learn from their mistakes. Again, just my .02$
