A pale shrimpbogy with two narrow diagonal bands on the snout and cheek, followed by 5 broader reddish to brown bands with brown spots in the interspaces, a yellow anal fin with red and blue margins, and a reddish arc on the caudal fin.
Shrimpgobies share burrows with alpheid shrimps. The shrimp excavates and maintains the burrow, while the goby watches out for predators.
