I have a planted 38 gallon tank with a pair of apistos and 4 ottos. I am heading to the lfs in a little bit to get an angel, or maybe 2. I would like to get 2 of them but am not sure if they will fight. They will be young ones, so there is no way to tell if they are male or female. So...........if I get two of them do you think they would be ok if they were both male or both female? Or should I just get one? I also plan on adding some pencilfish to the tank if the lfs ever gets any in.
