Goldfish breeding.

2 weeks ago I saw my male goldfish chasing the female goldfish.Is it a mating behaviour. Also I noticed that they have some pimples on their gills.Is it normal?

 

Can you get a picture of their gills?

 

Usually, male goldfish will develop white pimples around their gills around breeding time, but a picture would confirm...

 

TexasDomer and Five 97 , I am out of station . So I can't post a picture. But definetly I will post a picture when I return home.

After research I saw that the pimples are same with the other mature goldfish.
Maybe they will give some eggs.

 

Here it is.

This is the best I captured. He is a restless guy.

 

@TexasDomer and @Five 97 any ideas from the pictures ?
Looks to me like tubercles.

 

Looks normal to me!
