So I have a couple of male croaking gouramis (Trichopsis vittata). I am confident that they are males based on descriptions that I have read and because they spar quite often. Last night, I noticed the dominant male guarding a small bubble nest. I was surprised to see that given that there is no female, but I let it go for the evening to see if it would remain a fairly simple bubblenest. Perhaps something in the tank triggered it, but since there are no eggs, I was curious if he would abandon it. Well the next day, he was there guarding the nest. He normally is only "aggressive" towards the other male, but he normally leaves the other fish alone. Now it is open season on anyone coming within half a tank distance to the nest. I decided that perhaps this has gone to far, as I don't want a lot of split fins. So I put my finger into the nest to destroy it and to see what it felt like. Meanwhile, the fish were swimming around the little circle I use to feed them. The male chose to make the nest right next to it. The fish were circling probably because they wanted to be fed. Anyway, I stuck my finger into the nest and little "bubbles" began to shower down. What was even more interesting was that the fish were eating them. I bent down to take a closer look, and I realized that these bubbles were clear circles with a white dot inside. The fish ate the ones that fell greedily (you'd think that I never feed my fish the way they are!). The dominant male also seemed to be eating them. I stopped destroying the nest, and I was wholly absorbed in what seemed to be an impossible. The male "laid eggs."
Is that what I am seeing? Is this he a she? What should I do? The nest is fairly messed up now, and he seems to keep catching the eggs, and spitting them at the surface. All of this makes sense with what I know about gourami reproduction. I took some videos on my iphone (its all I have). The quality is not the best, but you can get some idea of what is happening.
Please share your thoughts or opinions. If you have a source supporting your opinion, please share that as well!
You will see the nest and the male. I also included the video of my males sparring and croaking (turn the sound all the way up, go to a quiet room and you will hear it)

i can't see video, says no data received.
from your great description i would say you have a pair of vitatta and a breeding one at that.
it sounds to me as though the male was guarding a nest full of eggs.
i would do one of two things, either leave things as they are and let nature take its course, or move the pair into their own tank for the next spawn.
it's unlikely any of the hatching fry will survive in a community tank ans as his nest is no more, he is going to spend a lot of energy trying to keep what eggs are still there in the remainder of the nest.
let us know how things go
ps you could always try and hatch the remaining eggs in a dish with a slow bubbling airline. it is possible to do this.
