Thats me lost another fish this time i noticed it was swimming upside down so i am thinking swim bladder so do you think its been the harsh winter thats four fish in total i have lost all under a year old ?
first off sorry to hear this news alex secondly we need to find the cause.. Are all your levels ok chap ???? spring is coming and the filter will be struggling to cope . how deep is your pond alex ? as if its been like hear cold at night and sun shining in the day it will have an inverse affect of the koi.
the fact they are a year old won't help matters too a koi ammune system is better at 1+ years
sorry to hear this news mate have u noticed any of your fish flicking or behaving in any non normal way as of late but this cold is not helping like mark says regards steve
air should not matter in the winter cold water hold o2 in the water better , i would personally say that a pond that's one meter deep and if the weather is anything like i have had here ie sun shining in the day then the temp dropping 8 deg over night is bound to have an adverse affect on young koi with being there first winter too just adds to the conclusion as many dealers stock in high levels and feed min to keep costs down these fish would not be feed up enough to survive a long cold winter like we have had the past 2 years
this cold is starting to make me glad i am considering "heating" next yr.
