Platinum gourami - male or female?

Hi all. I have this platinum gourami for some time now. It was 2.5 inches when I got it and has now grown to 3 or little over. The doubt I have is - whether its a male or female. I have read all the articles available on the net about the rounded (for female) and pointed (for male) dorsal fin, but still not able to make the difference. Obviously this needs someone more experienced with fishes and gouramis in particular. Could someone please look at the pics I have attached and let me know if this platinum is a male or female? Sorry about the slight hazy pic - the little guy moves a lot and its difficult to get a better pic.

I am planning to create a breeding tank. Can I pair this with a pearl gourami or are they different and should not be pair? What can I pair this platinum with?

 

I think this is a female, this fish is a color variation of the Blue three spot Gourami. So has the same requirements as that fish
You can pair this fish with a Blue Gourami, Golden Gourami, Cosby Gourami. But not a Pearl.

Thank you... I just want to be sure its a female before I get a male . I have heard males are more aggressive and do not want to end up with two males.

 

Personally I'm not so confident that is a female. It looks like it has a rather large and somewhat irregular shaped dorsal fin for the size the fish is currently, which should be around the boarder of when they become sexually dimorphic.
I will say I'm not great at sexing young fish but this looks like the two platinum's I had which I thought were females until they both matured into lovely looking males.

Not sure of your setup but these fish are going to need a place to go. Keeping a pair together isn't a good idea for the most part as they create dominance based hierarchies. When there is only two, one often will get bullied to the point of death. Keeping them in a larger group is a must in my opinion.

 

two females are just as annoying and aggressive with each other as having two males if the tank isn't large enough to give them plenty of space and not have to cross paths constantly. The dominant fish harasses the submissive fish. a much large tank can stop this from happening they won't cross paths as much, have a group of 4 females can spread it out and keep the dominant female busy.
one male and one female is a no go, the male will harass the lone female to death, same way he would harass another male, just not for the same reasons. One male and a couple females speads out the harassment also.

it looks female to me.

Then I guess I will wait for some time maybe. Could you tell me how long your gouramis took to reach maturity or sexual dimorphism from a stage like this?

I currently have this in a 80 litre tank with some platys, but will move it to the 330 litre tank which I have recently setup (its cycled with 0 ammonia and 0 nitrite). It has become more aggressive of late, which could be because its reaching maturity? I was planning to add one additional gourami in that 330L tank, but will add this then, wait for some time, and then add more - multiple gouramis to spreadout any level of aggression.

Hope that will work.

Thanks for the info. I will add more to make a group and spread out any possible aggression. I will be shifting this to my new 330L tank. Its a planted tank and I have tried a blackwater setup (tannin) to give a more natural look.

Maybe a month or two, not quite sure it was a while ago now. Fish develop fast especially in larger tanks when fed properly. So it shouldn't take too long either way.

330L tank, but will add this then, wait for some time, and then add more - multiple gouramis to spreadout any level of aggression.

Sounds good to me
