I'm fairly new to all this, I got my 3g tank a month ago with a cherry barb. Thats where it all started for me. Now I've got 1-20g, 1-10g, and the 3g. In the 10g I have 2 male dwarf gourami, one is a sunset (I think that's what it's called) and the other is just a dwarf. I read originally, or so I thought, that male gourami are territorial and will fight if they're the same kind, but of different kinds, they'll steer clear of each other. I'm wondering if mine are too close alike maybe? They fight constantly. The Dwarf I had to put in the 20 cuase he stressed himself and he's the aggressor. I don't know what to do but I don't want them in seperate tanks. Suggestions? A recent article I read said they're fine unless you only have 2, in other words, that it is best to have 3 to prevent the fighting. Also, I read to have several plants, but how many is several? I'm just really confused. Wife and I are considering a paradise blue gourami to see if that helps out, by adding a 3rd. Right now we have 3 plants in there, all are tall reaching to mid or top of the tank and they're kind of spread througout the tank.
