This is just heart breaking to me, I will always remember the feeling of being so scared and worried for the little fish that needs you so bad. Looking in a tank with a helpless sick fish that needs you but knowing you cant do anything is the worst feeling ever.
I just dropped in on this thread but was wondering what you are doing for him as far as treatment? I saw that you have experience in rescues but I am here for you and if you need any advice or have questions I only a message away. Good luck with this treasure, I wish him the best and hope he makes it through the night!
He's currently in a 1 gallon tank, heated to 80 degrees, and it being treated with my go to mixture of aquarium salt, stress coat, Vitachem and Indian Almond leaves. He has yet to show any interest in food after the second day I had him when he ate 1 pellet, poor man.
