Had bought 100 lot grab bag of mixed fin koi and every one of them had died! I am an experienced fish hobbyist and these fish died within a week! Arrived at my place a few dead already fray fins fin rot bacterial infection pop eye cloud eye and all died.I contacted the company and they refused my refund stating I didnt know what I was doing by raising a Japanese carp!!!!!!! In the mix of koi were goldfish as well !!!!!!
