Dracula goby and pistol shrimp pair

Maximum size: fish: 3", shrimp: 2"

Minimum tank size: 10g

This pair will create a burrow in your sandbed that they rarely venture very far from. That said, it's one of the coolest symbiotic relationships to watch. The goby catches the food while the shrimp tends house and protects the burrow with his threatening, pistol-like snapping.
