I made a mistake, I saved a Vieja from a 14"+ Arowana, and I put it in my tank with another BIG fish...
Few hours later, it got beaten up so badly that all his scales went missing
He's breathing, and struggling to live, but I am not sure if I should end his life, or just let him be?
What do you think?
