Yellow Watchman Goby Care Guide

Overview and appearance

The Yellow Watchman, also known as the Yellow Prawn or Yellow Shrimp Goby, is one of the unique and desired fish available for a saltwater aquarium. It is a peaceful fish that is a mix of yellow and brown colors with small amounts of blue.

Although these fish are very small and overall peaceful, they are very territorial and will not tolerate other Gobies in the same tank even if there is plenty of space. The only exception would be if they are a mated pair that was introduced into the tank at the same time.

A popular behavior of the Yellow Watchman Goby is it will form a special bond with a Pistol Shrimp and they will become a great pair. The Goby will protect the shrimp from danger and alert it when trouble should arise. The shrimp will dig and make a cave for them both to live in. So they both benefit from the relationship.

They require a sand substrate and plenty of hiding spaces in the tank. Even though they are easy to care for, it’s important to have stable water parameters as poor water quality can easily affect their health.

A great thing about these fish is they don’t require a large tank. A small or nano tank is fine for them. They will only grow to be 3-4″ maximum size and are suitable for beginners.

Temperament – Are Yellow Watchman Gobies aggressive?

As mentioned above, these fish are generally peaceful, but they are territorial and will not get along with other Gobies. Unless they are a mated pair. They will get along with other peaceful saltwater fish, and they will appreciate having a Pistol Shrimp to socialize with and form a bond.
