My male dwarf gourami keeps building bubble nests even though there's no female. I know this in normal for male gouramis and I hope to get him a lady friend as soon as I can. How big are the nests supposed to be? This nest here is the biggest he's made before, and he's not done with it yet. It's probably an inch long in some spots. http/s1283.photobucket.com/user/Passamaquatty/media/image_zps0fa1e0f6.jpg.html
