Blue Spot Watchman Goby
Blue Spot Watchman Goby, Cryptocentrus pavoninoides, occurs in two color variations, which some believe to be sexual color variations. One variety is gold with black bars on its body and, true to its common name, blue spots on its head. The second variation is a green-yellow fish with blue spots on the head trailing through the body. This is one of several Shrimp Gobies found in the oceans. If present, this fish will gladly share its sand bed burrow with a Pistol Shrimp of the Alpheus genus. It will also build burrows in the absence of a Pistol Shrimp; helping to keep the sand bed well stirred. Because of its penchant for burrowing, the substrate provided should be fine sand. Its white body with vertical orange striping is accentuated by a larger black blotch on the dorsal fin. Like other members of the Goby family, this fish is a skilled leaper and requires a tightly covered aquarium. The Blue Spot Watchman Goby is more peaceful than other Gobies in that it is much less territorial against others of its species and family. It does have the potential to eat smaller ornamental shrimp, but is otherwise harmless to other fish, invertebrates, and corals. Be sure to house it with compatible aquarium mates that will not be overly aggressive or confrontational to the Blue Spot. Great singly or in groups, this reef-safe fish readily adapts to a diet of frozen or live shrimp such as Mysis Shrimp or Brine Shrimp.
Approximate Arrival Size for Blue Spot Watchman Goby: 2" to 4"
