I have gone to vinegar injections when needed.
Works just as well & will not clog the needle.
Some even use lemon juice.
CBB are so finicky I would use a filefish.
I have used lemon juice injections, but I've found peroxide works just as well to kill them. Started using it when I read an article about how it turns to water and oxygen so it doesn't mess with chemistry. Not sure how true that is (anybody an expert on this?) but it does the job. Some shrimp and hermits will eat the bodies after peroxide - but not after lemon juice.
