It appears to be in the genus Cryptocentrus, but after scouring the genus I couldn't find any clear matches. May be a really faded individual of C. cryptocentrus (ninebar prawn goby), possibly C. lutheri (Luther's prawn goby). Is this a pic right after he was added to the tank? He looks stressed. Regardless he's definitely a shrimp goby so getting him a large pistol shrimp would be good.
thanks for all the reply’s. Found this on fishbase.com. Looks like this one and may not have the reddish orange colors because of stress. Or as someone else said a female yellow watchman. She is in there with a maroon gold nugget. Had someone bring the fish in to me they were getting rid of tank. What do you guys think?
Ok moved her to another tank can see her better. Definitely looks like the female watchman in the thread above. Has the same white lines and tank body. Only this one has a dark orange/ red gill-under jaw area. Never seen that before.
