Green Mandarin Goby The Green Mandarine Goby is one of the most colorful creatures on the planet. Most beginner saltwater aquarium owners will buy one and kill one. These gobies need special care - live food and clean water. Primarily a bottom-dweller, the Mandarine Goby will "hunt" across the substrate and rock for live food to graze on. It is slower and more methodical than most reef fish, and cannot compete with more active or aggressive tank mates for food. IF you want a male or a female please specify on the order, but they are both exotic. Males just have a point on the fin. Scientific Name: Synchiropus splendidus Origin: Philippines Lifespan: 4 years Max Size: 4 inches Food: Live, flake, frozen Shipping Size: 1 to 3 inches
