ID this little goby?

It's about an inch long. I bought two of them today. I thought they were probably Trimma Cana when I saw them in the LFS, but now I'm pretty certain they're something else.

Now that I think about it, I'm not even positive it's a goby. LOL

looks like a Masked Goby (Coryphopterus personatus). same care as a trimma but live a helluva lot longer.

I believe you nailed it. Thank you!!

Speaking of Trimmas, what is their life expectancy in your opinion? I am interested in T. cana also. Those, and Eviota Pellucida, or "Neon Pygmy Goby".

If you hadn't guessed, I'm a nano guy (29g SPS). I've determined to stock my tank with only the tiniest fish, but plenty of them, to create the most realistic-looking scene, with a minimal bioload.
