Hi,

this is is my first post and I’m not sure if this is the right place to post but we have recently lost one of our koi to being egg bound - tonight after finishing work one of our koi looked as though it had been slit from tail to head on its underside I’m not sure if that is spawning related/disease or predator etc but it’s got me very very worried. after checking a couple more I noticed this mark on one of our koi - can someone identify what this is please? I’ve just dosed the pond with medifin as this is all I had available to me. Any help greatly appreciated
