Isn't it a bit heavy to say it is unethical to keep a saltwater/reef aquarium? I think that shows that the person saying this may have limited personal knowledge about the real causes of destruction of reefs. From what I have read, no personal knowledge, is that this hobby has a slight positive effect. So, the hobby likely has at most an insignificant effect on the reefs. Care for your animals as you would any pet and be personally moral in your care, but please don't try to tell me and other hobbyists that we are immoral or unethical. The hobby is enjoyed by many folks and it seems a bit much to be on a high horse and deem that the hobby is immoral or unethical. Why would anyone with these types of feelings ever get into this hobby? Why not keep freshwater were you can get all captive bred and not try to put a guilt trip on everyone that enjoys this hobby and are not unethical. My vote, these debates are pointless due to the lack of real knowledge by those proposing the sky is falling. No, I don't have my head buried in the sand on the issue, but when someone says that the "destruction" of the reefs began before this hobbby ever started than how would you conclude this hobby is unethical?
