Whose burrowing skills were quite showy
He sifted through sand
With a wave of his hand
And made a cozy home oh so lowly

But don't let his humble abode fool ya
For this goby's got skills that will school ya
He's got eyes on top of his head
And can change colors like a chameleon, it's said
This little fish is one cool dude-a!

So if you're looking for a fish with some grit
A Watchman Diamond Goby won't quit
He'll help keep your tank clean
And be the coolest critter you've seen
This fish is truly a hit!

Keeping Watchman Diamond Goby in an Aquarium

The Watchman Diamond Goby, also known as Valenciennea puellaris, is a popular fish for reef aquariums. Here are some things to keep in mind if you want to keep this fish in your aquarium:

• They are relatively small, growing up to about 4 inches in length.
• They are bottom-dwellers and like to burrow in the sand.
• They are peaceful fish and can be kept with other non-aggressive fish.
• They are known for their symbiotic relationship with pistol shrimp. The shrimp will dig a burrow and the goby will stand guard at the entrance, warning the shrimp of potential danger.
• They are active fish and need plenty of swimming space.
• They are omnivores and will eat a variety of foods, including small crustaceans, worms, and algae.
• They are generally hardy and easy to care for.

One of the coolest things about the Watchman Diamond Goby is their unique coloration. They have a diamond-shaped pattern on their body that is made up of small dots. They also have a bright yellow tail fin that stands out against their brownish-gray body.

Another cool thing about this fish is their behavior. They are active burrowers and will often move sand around in the aquarium. They also have a unique swimming style where they will dart around the tank and then quickly bury themselves in the sand.
