pale green watchman goby

[kurt72]

i bought a "adverstised" yellow watchman goby 8 months ago from the LFS. only thing is, it's not yellow. i have searched all over the net and i can not seem to find the same light green goby like mine. i have just noticed lately, it is getting paler on it's top. it is perfectly fine. has a hearty appetite, spends all it's time hangin out with my tiger pistol shrimp. in fact, i lost 3 fish two months ago when i polluted my tank by overfeeding. and the only thing to surive were my pistol and goby. i even killed my snails and hermits. anybody who can help me identify my goby, that would be great. thanks.

They change color based on gender. I had a question about mine too. Here is a link to my thread about this:
