I have had my Yasha goby and Candy Cane pistol shrimp pair for around 2 and a half months. I put them in my tank and they bonded after about a week. I did not witness them pairing and moving into a cave but they did. The Yasha has been living in that cave ever since and is doing fantastic. I have not seen my pistol shrimp since they paired up at all. Not even a glimpse but also no corpse. I am wondering if I should leave it be or not. My worries are that the goby will eventually die from not having a paired shrimp or that the shrimp is alive and getting another one will be useless and cause a fight. Thank you!
