I bought it alongside a pistol shrimp about a week ago. The day I got them I acclimated them in the same container, and when I release them they went their separate ways. That was the last time I saw the shrimp, and the goby was out in the open up until this afternoon, then he went missing. I peeked into his burrow with my phone flashlight (probably wasn't the best idea if he's still in there) but no sign of the goby. My original concern was the shrimp being missing and now I have a missing goby. Could it have relocated burrows? I tried looking at all angles of the rock where it's burrow is. No sign of a new burrow.
