Need to ID this for a friend.

 

[duanes]

looks like one of the Goby's, perhaps genus Eleotris, similar to (but not exactly) the species below.

Definitely a goby, more than likely brackish.

Maybe a marbled goby?

 

[Deadeye]

Marble goby (actually a gudgeon) has a huge mouth, this definitely has the typical small goby face.
About how big is this guy?

 

[duanes]

One thing you may want to consider is the goby's chameleon like ability, to mimic, and change color with surrounding habitat, at a moments notice.
The color of the substrate in the OP may influence color pattern, and even spotting prevalence.
Here are all shots of the same Eleotris individual I kept.

Freshwater, and is 13 cm. I'll send him picks of yours, duanes.

Could be Elodeus Picta. What do you think?

 

[Deadeye]

I think it’s an eleotris goby, I don’t think it will be easy to get to species though. I can’t find any that has the spotted face and the lined back.
