water changes should be done weekley, i do 50% every week and some times twice a week. pellets are different, they have different protein levels fat levels etc. a varied diet and a clean tank is key to having a healthy oscar.
how long have you had him now??? i would do a 50% water change atleast once a week when he is better. but for now do 30% changes every other day and add aquariam salt.
