im thinking of feeding my ckf frozen lance fish or frozen smelt, but will it make it more aggressive? hes 5 inch at the moment. Also i have a 12inch poly. senegalus and a 12inch Channa aurantimaculata and a 5 inch poly. delhezi will this have any affect on these guys?. I currently feed them twice a week on market prawn and a staple of hakari pellets.
