Need some advice have two rapps orinos .One is really starting to outsize the other.In the past few days the bigger one has been bumping the smaller one to enough to show a little visable damage on fins thinking about moving larger one and getting a few more from rapps before they are gone.small one is 2.5 large one is 3.5 now rapps says what he has left are 2 to 2.5 Would I have same problem if i got more of rapps smaller ones.Iknow bullying is always a posability but am i setting myself up to fail .?
