These colorful species are found on the south part of Japan up ti the Yaeyama island. As well, they can be found in Palau and Truck, the islands in Micronesia.
Their natural environment is in the Indo-Pacific where they inhabit shallow lagoons and inshore reefs, especially around rubble beds or dead corals, which offer them protection and privacy. This means, the Yellow Watchman Goby will require an well-established 30 gallon or larger reef aquarium with plenty of live rock and a sandy substrate for survival.
They are easy to feed, and readily take vitamin enriched brine shrimp, mysis shrimp, finely chopped seafood, and frozen commercially prepared food for marine fish.
Goby fish are reef safe and peaceful marine fish. They adjust well to aquarium life and are not aggressive to other marine inhabitants, but it is territorial, and will fight with its own kind unless they are a mated pair. If you are looking for a unique species to add to your marine tank, consider introducing a species of goby!
