Yellow Watchman Goby
 

My Yellow Watchman Goby has turned white. Not a pure white but it is significantly lighter in colour than when I first got him and I don't believe his colour has changed gradually since I brought him home a couple months ago. Has anyone had any experience with this? All my tests came up clean showing nothing abnormal. Thanks for your time

what are you feeding him?
try using a macro algae to supplement the diet.
I feed mysis, bine shrimp, and macro algae with a lot of carrotein and my watchman is bright yellow!

hope that helps

I believe that means she's a female.

Even still, she should be yellow. Do you have a sand bed? Mine sifts through the sand when he's hungery.

Now i don't guarantee anything, But i was pretty sure i read somewhere that the female will lose her yellow as she matures.
As in this mated pair.

I thought that only occured when in the presents of a male YWG.

You could definatley be right. I dont really remeber the details about what I read, Just that the gray ones were the female.

My female is by itself and has only female coloration.

Same with mine.

Same thing happened with mine. Oh well, we still love (him/her). http://www.canreef.com/vbulletin/showthread.php?t=21164

Several sources report having them change back and forth. Weird.

In that picture you have there my goby's entire colouration is like the lighter colouration on your female goby. I've been feeding her some new life spectrum and some brine shrimp and mysis which she seems to really like. YOu think that's a good enough variety?

Hmm, do you guys have a pistol shrimp with your YWG?

No, not a pistol shrimp. But I do have a cleaner shrimp.

I have a pistol shrimp with my YWG and they do hang out together but not all the time.
