I have a Yasha Goby I had quarantined for 2 weeks and put it in with a pistol shrimp 5 days ago. The pistol shrimp has a full cave and is happy and healthy. The Yasha Goby I have not seen a glimpse of for 5 days now. Like not at all. I have no clue where in my tank he is. Ive tried feeding all over the tank to get him to come out. He still hasn't paired up with the shrimp and Im really getting worried. Should I cut my loss and say he's dead or is this normal?
