Diamond Watchman Goby
Valencienna puellaris
The Diamond Watchman Goby is one of the most functional gobies in a reef aquarium as it digs deeper into the substrate than most others making it a useful fish to have. Multiple specimens should only be housed in pairs
It requires a tank of 200 litres or larger with plenty of hiding places and a sand substrate to dig a cave in. Does well in a reef aquarium and doesn't bother corals at all, they will eat bristleworms.. They adapt well to flake and frozen foods and like frozen meat
Approximate Purchase Size: Medium 4cm - 6cm
