Oranda Goldfish: Chasing, Playing, Bullying?

HI guys, just got two new Oranda goldfish for my 40 gallon breeder. Bought them from eBay. They are about 3". The seller said around 8-10 months old. I asked the seller for a male and female and he said he would do his best to sex them for me.

I was wondering if their behavior was normal. Yesterday and this morning they didn't bother each other. Today, there seems to be some chasing going on. I wanted to share a video of what I was watching and see if it's normal. This is my first time keeping Oranda. I just want to make sure one isn't getting bullied.

Thanks!

 

Can you take a closer picture of the oranda ? Generally the males have tubercles on the operculum during the breeding season.

 

This is a picture of the guy who is nudging.


And again. The nudger is in the back.

 

CindiL you keep goldfish, correct? Any idea on the behavior in the above video?

 

To me It look a male trying to get a female to mate. My one male does almost the same thing but a lot more aggressively. I've never breed them but I do know mine doing so was a male (breeding stars) and almost sure the other 2 were female. He did however also do so to my other male.

Good to know! Thank you!
