Its head is reddish-orange (hence the name) and its body and fins are black. It reaches a body length of 4cm. This species is said to be monogamous.
Lives on the branches of Stylophora coral.
Spotted this tiny goby at a depth of about 15m, during a dusk dive at Dayang Beach, Talikud Island. Not sure if the coral it was associated with was a Stylophora coral -- it sure looked like a Pocillopora.
