i would be surprised if etomidate is available over the counter, and if it is it shouldnt be. also i would never trust some secret formula to anesthetize my fish and keep every other life form alive and well. if it is eugenol you should be able to id it by the smell.
I disagree. If you have established reef tank that has been working well for sometime, taking down the reef will almost certainly kill a lot of life that has grown on the rocks according to available light and water flow.Sure it will take you a lot of work to remove the rocks to take out one fish, but it is safe.
That's a good point :thumbsup:I think the ultimate problem here is that no anesthetic can be used and then just left in the tank...invertebrates or not. When I've used MS-222 to capture a fish from a tank (rarely), I always end up doing a 100% water change to remove it. To find an anesthetic that will allow one fish to be removed, and then for the anesthetic to remain in the water is not likely in my opinion.....

Some time ago, there were some people here on RC that said what they do is wait until 3am, then suddenly turn on the aquarium lights. As the fish bump blindly around the tank in shock, they just net the ones they want removed. Crazy I think, but they were seriously in support of that idea....
