The "new" in thing is to cycle without fish, as I have learned, but being an old fart who has been with fresh water for 25 years, some people still use fish for cycling. And yes my LFS
did recommend using a damsel for cycling. But I am surprised at how "nasty" people are on this site, when I am only looking to learn about saltwater fish keeping. A less direct approach would be appreciated instead of a scolding. But I do thank all those who responded for your help, and I appreciate it.
