Hey all! I have a 37 gal tank with 4 kribs, 2 male and 2 female. I have a possible pair that when around each other are not aggressive to one another but if the other unpaired male and female try to swim around the other pair, the pair chases after them. Is this a sign that I could have a possible male/female pair?? If so, what should I do about the other m/f who can't seem to get there act together??? I do know for sure about the sexes. The other female "sits" near the top of the water, at an angle, in one of the corners on the tank. The male still swims about, but gets chased off by the possible pair. Ideas appreciated! Thanks
