A couple days ago I found a tiger pistol that was a perfect size for my smaller YWG (both ~1"). Brought the shrimp home, managed to easily catch the goby, and put them in an acclimation box together. Everything looked great, shrimp was next to goby, touching him with antennae. Gave them a night in the acclimation box just to get them used to each other, and then morning after (yesterday morning), tried to drop them right next to each other. The shrimp scurried into a hole of one of my rocks and the goby lost the shrimp, but did try looking for him. Came back a few hours later and the goby had decided to take refuge in a cave far from where the shrimp had ended up. As of this morning, the goby is still in the same cave, and I have found where the shrimp decided to make its burrow, not close to each other. Goby eats but refuses to come out of the cave to look for the shrimp, and the shrimp is barely visible as it is barricading the only entrance to his burrow with sand. Do I just have to give it more time, or should I try to direct the goby toward where the shrimp is? Only thing concerning me from a pairing perspective is that the goby hasn't made an effort to look around and is just sitting in the same cave I found him in last night.
