so my b&w pair (acquired from furfeet) have finally seperated themselves from my true perc pair (who are a confirmed pair) and have chosen a spot in the tank to defend....my percs host all my nems and my b&w's got the rocks lol....anyways the b&w male and female are both showing the cleaning behavior and are doing the spawning motions in the pit but with no eggs....my question is..if i put some flat rock or something there will they lay eggs or am i just trippin?
