I'm fairly new to saltwater (roughly four months in). I have a 40 gallon breeder tank with normal stats (nitrate, nitrites, ph, etc. all within acceptable ranges). I have two clowns, one turbo snail, one starry blenny, and one royal gramma). I was thinking of adding one more fish in about a month, but I can't decide on what to get. I really wanted a yellow watchman goby, but I heard they don't get along with blennys well. Any comments on that relationship or other suggestions for peaceful fish would be appreciated.
