New To Gouramis, But Not To Fish Keeping

[hughessomefish]

So today at the petstore I saw these beautiful Sunburst Gouramis aka Honey Gourmais I believe. So I bought Three of them, I believe atleast 2 of them are opposite sex, because Of seeing the male try to mate with the female, but thats just a guess. So how do I tell if there a male of female, and What do I do if they start making a bubble nest? So basicly I am asking How to tell if there mateing/ their sex. Also I am asking for info on breeding, I am not blanning to try and make them breed, just its a fact That I know happens in fish tanks, I haven't been on the fourms in awhile,Hows it been? But this is my Third year in fish keeping, I just have never gotten Gouramis, I am more of a livebearers, tetras, and cory's type of guy. But hey saw these guys and they where strikeing!

The top ones a male,

but if you get 2 females its likely to happen, but think you need floating plants to 'help' them along
