Confused

Postby KGB13 » Wed Aug 09, 2017 2:17 pm

Newbie here. Been 3 days with my new pair of green terrors. My first cichlids and I m excited. The guy at the petstore told me that the larger one is male and other one is female. The tank is 40gal. The larger one keeps on chasing the so told female and I am worried. Is this normal? Also confused with the sexing. Attached photoes of both.

They both look like males to me, the females have darker pectoral fins than the males. I used to keep them years ago, but a 40 gallon is on the small side for that species also.

If it continues, I'd throw a divider in the tank.
Over time, if they seem to show interest in each other, then pull the divider and monitor, supervised. If things get really rough then put divider back and try again another time.
Not unusual for many pairs of cichlids to have to be regularly divided, especially with out other cichlid tank mates.
I enlarged your pictures to look at both your GT's and I am not certain on their sex. I believe the larger is male (though not 100% certain) and lean towards the smaller being female. Body shape, lack of coloration on the fins, and small pelvic fins all point towards female, IMO.

The fins look exactly the same on both fish... Females have black pectoral fins. The smaller one just isn't as developed as the bigger male and obviously not going to be as colorful because he's the the sub. I've kept green terrors and bred them...

The smaller has two bands in the body, that makes me lean towards female.

Thanx for the suggestion. The chase is especially after the feed. If they dont get along in a day or two, will go for the divider.

Thanx mate. I will put the divider first to solve the current issue first. Lets see what they will grow up to.

Both came out to be female. Both laid eggs.

Yep, they both have black pectoral fins now too. Must have been stressed and a little bleached out when you took the first pics

First of all, they are called pelvic fins. Pectoral fins are pretty much colorless on all cichlids.
And yes of course , young females in breeding coloration often have dark pelvic fins. At this point, in breeding color or especially with eggs, there are usually a half a dozen other traits that also point towards it being female.
IMO, in general, not a very useful trait to distinguish the sex of GTs. IF you were to use this solely......entire tanks of young GT's at the LFS would be sexed as 100% male.
Just by guessing, you have a 50% chance of getting the sex right. To get both wrong, it's pretty telling that it is not all that useful nor reliable :lol:

Funny because I've bred them and it's not been the case that you're presenting... If you're so smart and think you're some kind of expert then why did you get it wrong too. Geez what a douche...

I made it quite clear I was not certain on sex.
And it's one right, one wrong.
But after the second picture was posted of the smaller one , I think it was even more likely that it was female, though still not certain enough to go out on a limb and say with certainty.
As the OP mentions, the white stripes are often a fairly good indicator of a GT being female. Not that male could never, ever express this trait.....only that it is typical of female and much less common of males.
You were pretty adamant on the sex of these fish. Insulting, resorting to name calling and making excuses does not change the fact it is not at all reliable to sex GTs this way.
