Sexing Goldfish #1
Hi all, Ive been looking into how to sex goldfish as i wanted to find out what gender my fish are, my calico oranda has a convex vent which i believe means it is a female and my chocolate oranda has a concave vent which means it is male (no breeding tubicles at present) but their behaviour seems to suggest the opposite the calico chases the other one all around the tank and nudges it up the behind quite alot at the minute have i got the sexing wrong or have i just got a very forward female

Re: Sexing Goldfish #2
I'm ot sure about vents but the breeding tubicles seem to appear at about 10-12 months.

As for behaviour I think the ladies can become amourous

Re: Sexing Goldfish #3
Opposite to humans.

'Outie' vents are females, 'innies' are male. Breeding tubicles, as Jon said, seem to appear at about 10-12 months on males.

Fish sometimes get confused though. Suey had 'Winston' who assumed all the fish he was with were girls (despite being all males) so he had to rehomed. Too much friskyness!

The fish personality dictates most of this

Re: Sexing Goldfish #5
Thanks guys, it seems she is a female then and a very frisky one at that! the poor male cant go anywhere without her chasing him at the minute but luckily he doesnt seem to mind,the ranchu just looks on totally bemused ( the jury's out on the sex of him/her so far just have to wait to see if breeding tubicles show up)

Re: Sexing Goldfish #7
I definately think our ranchus are related Jon (Bumble was from Ripples too) as they look and act pretty similar by the sounds.

Re: Sexing Goldfish #8
Dunno, my ranchus were pretty enamoured with two other fishies before, I didn't know what was going on.

That was a year ago and they've shown no breeding stars or breeding behaviour since, so I think they've not met the right fish yet.

I've never managed to sex Ronnie, so he's defaulting to male :D

Re: Sexing Goldfish #9
Water temperature can be a factor with amorous behavior too.

When you do a water change try and get the new water to the same temp as the tank, if its colder water going in the chill can set them off

Re: Sexing Goldfish #10
Hi jellybean, ive read that cooler water can trigger this behaviour but i always leave the water 24 hours to reach room temp or top up with boiled water from the kettle to get it up to tank temp before doing a water change so still unsure whats triggering if off but at the minute she's very frisky hope it settles down soon or the poor male will be worn out.
