Strange Goby Behavior

[BrianBell1974]

I have had a yellow watchman goby in my reef for 5 or 6 months and he has always been very yellow.

Approximately 3 weeks ago I added a diamond goby to the reef. I was worried they would fight but it appears to be the opposite.
They share the same hole and appear to have become mates.

I have read when you put two watchmans together one would change colors to almost white to clear with a black head and become the female.
My diamond is the color you always see in diamond gobies but the watchman has changed to the white/clear with a black head

At first I thought the watchman was stressed but if so I do not think they would share a hole and go everywhere together

Has anyone else experienced this and is it possible for them to be mated.

Mating won't work: they're too different, IMHO, but the yellow is a dominant-acting creature that runs his tank. He's evidently decided to chill out and be calm and let the other guy do it all.

Thanks, I figured there would be no physical way for them to mate but maybe just mentally the yellow could be seriously confused LOL

It is pretty strange to see a watchman so submissive. His yellow color is completely gone and does not appear to be stressed at all.
