Where do you live, b/c I cant find females anywhere. You could get a apir in a 55. The male will make a bubble nest if you provide him the right environment. he will guard the nest, but mostly just chases the other fish away from it. It is very cool to watch. If you got more than one male I would up the female ratio from 1:1 if possible. You could also get 2 males, each from a diff species. However, Pearls tend to like a group to be in. I have 3 dwarf males in a 120 and they have really divided up the territory. Two are making bubble nests in each corner while the third just hangs out. They don't pick on him but he has lost some of his color, poor little guy. Honey Gouramis tend to be more peaceful and stay small like the dwarfs. Maybe one of each of those would be okay, but I think a male and female dwarf would keep you entertained. If the store would let you, get 2 females. that way the male doesnt harass the one to death. They can be similar to Bettas in that way.
