Emerald Crab Troubles

[SurfTrack]

I have a 15g cube, and one emerald crab. Two days ago, I picked up a yasha goby and pistol shrimp pair. They’ve been hiding and digging their burrows for the past two days. I JUST saw the goby for the first time and tried to spot feed outside its burrow: my emerald crab RUSHES to the entrance of the burrow, takes all their food, and now won’t leave. I’m convinced I have to remove it — thoughts?

A pair of long tweezers should do the trick. I would banish it to my back chamber.
