Pairing a Watchman Goby with a Pistol Shrimp
I bought a bonded pair of a Watchman Goby and a pistol Shrimp about 6 months. Recently I think my Watchman Goby may have died, I haven't seen him in a few days and he is normally on the rocks out front of their shared burrow.
If indeed the Goby has died, can I purchase a new Goby and expect the pair to form a relationship. Are there special steps I need to take to get them to bond?
Thanks in advance
