I got my baby yellow watchman goby a few weeks ago, she immediately paired up with my candy cane pistol shrimp and sleeps in the burrow at night.. but during the early day before the lights come on shes normally swimming around. is she just exploring while my other fish are asleep or maybe looking for food? eventually before the lights come on shes back in the burrow but it always concerns me because my old one never left his burrow.
