thanks everyone. I turned down my heater its at about 79 from 81. we will se what happens. I do know that knives are very strong fish so I hope this is just a phase. I will not separate them unless damage is being done or one is not eating. I am going to ride this out and experiment with some things. thanks again. if anyone has any more ideas please feel free to share.
