I have 2 Dwarf Gouramis, both males, and they always are making nests. Usually one at a time. Of course during this time they do not get along so well.
But they again...they run off the other fish as well.
I personally love my gouramis. Both of them have their own personality. One is very shy and hides from me (unless its feeding time). They other one shows off for me and hangs out in the front of the tank.
I would recommend them to anyone!
