Today I noticed one dwarf gourami constantly is chasing and nipping the fin of another. I heard they belong in groups, so why is this happening? It doesn't bother any other fish in my tank...just the other D.G.
Why are dwarf gouramis fighting

Male Dwarf gouramis are pretty aggressive for their size, aren't they? "Out of sight, out of mind" so adding plenty of floating plants, like Water Sprite, can help cut down the size of each territory, but it may not be enough.
Gourami territory-holding is closely linked to the water surface. If the loser is being crowded down to the bottom, like behind the heater, better get him a home in a friendlier neighborhood.

They are very territorial and can be highly aggressive even towards non-DGs. What size tank do you have them in? Are they both males?
They're in a 55 gallon. I'm not sure the sex of them...they look exactly the same..if coloring determines the sex? The bully is just a little bigger then the other one.
I bought two D. Gouramis at the LFS when I started my putting fish in my 29G tank. They were selling them as male/female pairs only. I had this problem as well. When my tank was gettinga little overcrowded, I boughta 20G long and put them in there. The male doesn't chase the female as much in their new home. Are they like bettas where they don't like the females unless they are spawning? I know I have a male and female because the male is much more colorful than the female. Lots of plants and a tank that is longer than taller is better for them. Check my album in my sig for pics of my D. Gouramis. Good Luck. 
I kept male DGs together for years without more than mild chasing, so it puzzles me to read so many reports (here and on other boards/newsgroups) that they're aggressive. Maybe I bought a bunch of pacifists?

They get aggressive when there isn't much space.I've kept 2 blue guoramies or 2 spot guoramies males with little problems.
Oh my God, my two dwarf Gourami's fight all the time. I think they are both male. They get into this weird "Fighting" position--their bodies kind of curl away from each other in a standoff and then let the nippin' begin. One time the larger one nipped a chunk of flesh off of the top of the smaller one's head! They are also very territorial with the other fish--especially the newcomers. My new Gold Ram Cichlids can't go near them without getting scared half to death.
