Definately a Paradise fish...sometimes called a Paradise Gourami. Pretty tough little critters. I have one 3" (TL) male in a cichlid tank with 3 4" Gold Saums and that little Paradise punks them out on a regular basis. He came in with a shipment of fish that I ordered and I just chucked him in there thinking he would'nt last long...that was a year ago!
This fish IS a paradise fish, Macropodus opercularis, as several members answered in THIS THREAD you posted some time ago. I believe it's the same fish in another pic, isn't it? Don't post two topics with the same question and two different pics of the same fish. Post both pics in the same topic and ask ONCE. If you don't think you got the right answers, posting the same question in the same place is USELESS. No offense intended, but in this case you should post it somewhere else, not in MFK.
If you simply didn't remember where you posted it at first, you could solve this problem by doing a research for topics posted by you on this subject or simply subscribing to your own post. Much better than posting it again. BTW, your original topic is in the link above ("THIS THREAD").
