I love dwarf gouramis in fact its all I have in my tanks. I have 12, 6 in two tanks. They can be a little mean to one another it seems when there are 4 or less. I kept all males for about a year or so and when I decided to try breeding and got females all the males aggression died, they do seem to be more comfortable in the larger groups....*hint-especially with females*. I had the problem of finding females which wasn't possible locally. I ended up ordering mine online, I guess LFS's don't carry the females because they are the dull colored smaller counterparts and "don't sell". I actually like them the regular dwarf females are silver and when fed well have yellow tiger stripes. I also have 2 neon blue and red females, just a duller ALL neon coloring and smaller once again in size. Breeding them is actually very easy and amazing to watch, just like betta's they need shallow (roughly 8 inches) warm water with no flow and they build bubble nests. My 20 gallon planted is my "front room tank" all my beautifully colored neon's are in there with a Betta.
