Thank you guys! DrVader thank you for the pictures, it lookslike my Cory had columnaris.
I thied to take pictures but all come out blurry
Here is the picture from 10 days ago. Cory that died is one on the top and it looks very white compate to healthy Cory. Maybe it is normal, I do not know, but white one developed columnaris and died. Picture was taken the day I brought Cory from Petsmart. It was probably sick already:huh:
Here are pictures from yesterday, probably useless because too blurry.
This morning in Hospital Tank
I moved Corys to hospital tank which they hate, interesting thing that they seem to do better even without any medicine. One cory was swimming fast and flicking, now it is not doing it anymore:huh:
What should I do, put tham back? leave them in hospital tank for a while? I got QuICK Qure, but I do not want to add toxic medication if I am not 100% sure.
Maybe they had flukes and they fell off when I put cories in fresh water? Please, do not laught..I am such a newbie
