Breeding yellow watchman goby

[Gustavo Hirose]

hello everyone, would like to know how to form a breeding pair of yellow watchman goby? There is sexual dimorphism in this species? hermaphrodite? any information would be useful!

For me it just happened this morning.
Here is the pair I have tending to a nest of eggs (the mass of light yellow just above them).
I've attached a picture. In my case I do not see much color difference between the two. Others have noted the female turning much grayer around the time of breeding. This is the first time I have noticed them lay a brood. I am assuming the eggs are really fertilized) which I do not know yet.

One of the two is usually near the egg mass and regularly turns upside down and fans the egg mass with its fins. Have a movie of this.

Take a look on MOFIB, lots of people breed them there. I believe them to be hermaphrodites, but not sure if protandrous or protogynous. Sexual dimorphism is present, but I don't think it shows until sexual maturity, one will be blue-gray, the other yellow.

Gobies can change sex, likely both ways. The larger one is, like with clownfish, the female. The best bet to get a pair is to either start with two little ones or a large and a small.

This pair, which used to be yellow when they were young, spawned every couple of months for 12 years. I didn't know which one was the female except she was slightly smaller.



This is her with her eggs



And here she is when I got her.

Wow that is amazing never seen watchman goby eggs, When are they hatching ?

They hatched about 5 years ago.
