I purchased this little fella with a pistol shrimp, however i was sold him as a saffron goby, which I know he isnt but the price was right ;)

He looks like a blue spot watchman too me, can anyone confirm or let me know what he is?

Thanks in Advance.

Ive seen this type of Goby..its a spotted enginerring goby...they sand sift typically aliitle deeper..they burrow into shrimp caverns. I never forget the first time I saw a Goby...I keep thinking.."why the long face" since my start I have fallen just head over heels for these very interesting reef safe guys! I will stock with one soon ...I really love the "nightwatchman" Goby..there the neon green/yellow ones! I think there more interesting than the blennies! They look so bummed out yet there not!! He looks great!
