I have a yellow watchman that I bought a year ago that was barely half an inch long or less. Now it's a solid 2.5 inches long. Anyhow, there are no other gobies in the tank.
How can I sex this critter? I'm thinking of introducing the opposite sex, not so much for breeding, just to have a couple. How can I tell male from female? I know there's some dimorphism in this specie I just can't remember what.
