I have a 30 long community tank. Ever since I got gouramis there have been bubbles on the top. usually they just floated around and such. A week or 2 ago I got another dwarf gourami. Before i had 2 red dwarfs. This one is very blue. They all have pointed dorsal fins, so I think they are all male. I'll get some pics in a little while.

So, I just noticed that the new dwarf is definitely building a bubble nest. It is almost half an inch thick, and is in the corner of the tank. It has lots a plant materia in it. He tends to pluck it off the filter intake. He has also included a sword plant leaf in there, bigger then the nest! He goes to the surface, takes in air, and goes under the nest to expell bubbles. Now, is he building the nest, or just acting weird? He occasionally leaves to chase around the other dwarfs. I have a picture of one of the other dwarfs. Thank you and I will get some pictures of all 3 and the nest.
