? for yellow watchman buffs

Yellow clown gobies may nip sps, but not yellow watchman gobies.

oops, you're right my mistake. Good to know because in my new tank I really want a watchman goby

Well Well look who's turning yellow again! I just don't get it lol

 

[RJ Harris]

Did it disappear for awhile?

 

[Wiz]

Not really. He did hide a little more than often. But never really disappeared

 

[RJ Harris]

You have two right? Based on the picture. Can you see in the back of the tank? It's possible you could have a breeding pair

 

[Wiz]

Yeah, could be. Such a drastic change though

 

[RJ Harris]

Yeah. My female doesn't change to dark gray till a few days before she lays them right back to yellow after

 

[RJ Harris]

Yeah. My female doesn't change to dark gray till a few days before she lays them right back to yellow after

my smaller one turn white after about 6 months of being with the bigger one. And stayed white for Months. Just now started turning back.

I have a yellow watchman goby pair that spawns every so often. I've had the male for seven years and the female for five (I had to search around for awhile to find a female). I wasn't aware they were spawning until one night a few years ago when I passed by the tank and noticed a large gray blob in the male's mouth. He was at the opening of their burrow and shaking violently the gray blob which turned out to be an egg mass. I immediately observed babies breaking free and swimming away from it. I'm a fisheries biologist that specializes in larval fish taxonomy so I had to save a few of the larvae to observe under my high powered microscope. Here's some cool pictures:

here's a YWG larvae(the very bottom) next to 3 clownfish larvae for size reference
