A hospital tank is always a good idea in my opinion. It may be beneficial to move the other cories in with him because 1( Cories are social and it may reduce stress if he has pals in the hospital tank with him and 2( treating the other cories could be a preventative in case they are eventually infected with what he has.Ammonia .25 ppm
