Chinese Zebra Bar Goby - Ptereleotris zebra
Size approx. 4"
Gobies tolerate other Gobies very well. Prawn Gobies will even share the same home & Pistol Shrimp! Sand sifter Gobies are independent, content to do their thing which is excavating the sand under your rocks to make it's home.
A mid column swimmer, the Chinese Zebra Bar Goby is neither of these & can be kept signally or in a group that will school!
