Hi everyone, I'm wondering if there is an easier or safer way to remove a fish besides draining the water or having superhuman speed. I have a friend who is interested in the hobby and has set up a twenty gallon tank. As I've been helping him out, I was going to give him a Royal Gramma and Pajama Cardinal as starter fish that he's always liked. But I don't want to harm them or any of my other fish during the process. What would be the best way to go about removing these two from the tank?
