The Yellow Watchman Goby lives with burrowing shrimp as part of a mutual symbiosis, a relationship that benefits both parties. Whilst a benefit to both the goby and the shrimp, this relationship is faculative, meaning that they have the capacity to carry out this relationship but it is not essential that they do.

The burrowing shrimp is capable to digging and maintaining a burrow in which both it and the goby can be protected from predators. It can also be used for breeding. However the shrimp is a little hard of seeing and so relies on the goby to be its watchman, hence the name. The shrimp uses its antennae to detect a reaction from the goby, which moves its tail to signal that it has detected a potential threat.

It is one of the easiest marine fish to keep and is generally peaceful to other species.

For the purposes of stimulating the symbiotic relationship described above, you will need to lay a deep layer of substrate and add some larger particles such as crushed coral to the sand in order to allow the shrimp to construct a burrow. The Yellow Watchman goby will tolerate most reef tank water parameters. Make sure you cover your aquarium so you don’t find a bright yellow corpse on your carpet the day after you put it in your tank.

Females are generally larger than males although there is very little else to sex them by. Eggs are laid by females in the burrow created by the shrimp and the male guards these eggs. Be prepared with suitable fry food should you try breeding this species.
