Video- View from under the tank of shrimp an goby
 

Apologies for the shaky camera, it's an awkward angle.

COOL

Thanks for sharing, my pair had the exact same thing going but on the side of the glass amazing to watch them interact and scuttle back into the burrow.

It's a pain because this is the only way I see them. The burrow is facing the back wall. I know the shrimp is still alive because of the clicking noise every hour or so :)

Finally got a picture of the pair :)
