The Goby species are some of the smaller fish species that are available to saltwater aquarium keepers. In general, gobies need an aquairum hood because they are good jumpers and a suitable substrate for the burrowing species.
Lythrypnus dalli Catalina Goby A cooler water goby that can be territorial with members of the same species. This fish won't live out its normal lifespan in a higher temp reef tank.
Valenciennea puellaris Diamond Goby
Diamond Goby Excellent sand sifter that is also quite hardy. Needs a live sand bed and will require supplemental feedings which shouldn't pose a problem since they will go after typical aquarium foods.
Elacatinus oceanops Neon Goby A cleaner fish that may help keep the other fish free of external parasites, stays quite small, but not very long lived.
Cryptocentrus cinctus Yellow Watchman Goby This goby forms a symbiotic relationship with the pistol shrimp. They may scrap with other goby species, so use caution when stocking.
Nemateleotris decora Purple Firefish In our opinion one of the most beautiful fish species available. They are rather hardy and great jumpers. A good fitting hood with no holes for escape is needed.
