Diamond Watchman Goby (Pretty Prawn)
The Diamond Watchman Goby is also known as the Pretty Prawn, Maiden, Orange Spotted Diamond, Orange-dashed, or Orangespotted Sleeper Goby. It was first discovered in the Indo-Pacific Ocean in 1956 by Tomiyama. The fish has a white head and body with distinct orange spots.
This is a very timid species that thrives in reef tanks and is known for its longevity. It should be kept in a 30-gallon or larger aquarium with live sand as substrate and an attached refugium. The goby uses shallow burrows in the sand for shelter, which helps maintain oxygenation in the substrate.
It is generally peaceful and rarely aggressive toward other fish. However, it can become territorial and may fight with other individuals unless they are a mated pair.

The Diamond Watchman Goby has been a peaceful addition to my 40-gallon reef tank. It’s active during the day and hides in the sand when startled. I appreciate its calm nature and how it doesn’t stress other fish. It’s a beautiful fish with distinct orange spots that stand out in the tank.

I’ve had this goby for six months now. It’s very shy at first but has settled into its burrow. The tank has live sand, and it seems to be thriving. I didn’t expect it to be so long-lived, and it’s still active and healthy.

This goby is a great choice for a reef tank. It doesn’t compete for space and stays out of the way. The orange spots are striking and add a nice visual element. I’ve kept it with a few other small fish, and it’s coexisting well.
