Diamond Watchman Goby or Pretty Prawn Goby
The Diamond Watchman Goby is also referred to as the Pretty Prawn Goby, Maiden Goby, Orange Spotted Diamond, or Orangespotted Sleeper Goby. It was first discovered in the Indo-Pacific Ocean in 1956 by Tomiyama. The head and body are white with orange spots. It is a very timid fish that makes a great addition to the reef tank because of its longevity.
The Diamond Watchman Goby or Orangespotted Sleeper Goby should be housed in a 30 gallon or larger aquarium with live sand as the substrate, and an attached populated refugium. The Diamond Watchman Goby uses shallow burrows in the substrate as refuge, keeping the substrate well oxygenated. It rarely becomes aggressive towards other fish, but is territorial, and will fight with its own kind unless they are a mated pair.
