I have been fighting tail biting with Koi, finally moved him out of the divided ten gallon and into a one gallon as it was getting to expensive to use stress coat + in required dosage. So his tail is slowly getting better, and over summer will look for something bigger at garage sales.
Now last night power went out in my bedroom. I sleep in the basement and my room stays mid- sixties. Couldn't do anything about it at time so just went to bed and around 9 this morning my dad helped me out. Well over night the temps in my tank went down and Arashi shredded his tail. Now the tank is reheating. Hopefully the low temps are what caused it. If I have any more tail biting problems I will only get PKs and females. It's so fustrating! And stress coat + is to expensive to be dosing a ten gallon all the time. I would QT if I had another heater.
Just my little rant cause I am getting fustrated with my two boys.
