I have an orange pike and oscar who have recently become intolarable of each other and have been fighting a lot. Despite efforts in order to dismiss the aggression such as dividers the aggression will not go away. Sadly, I have a feeling that this behavior will not go away and I am forced to have to have them separated for good. The two fish cannot be kept in the same tank so if you are interested in one of these fish keep this in mind. Pictures will be posted shortly. If you have any questions or if you are interested feel free to pm me.
