Are these oscars sick?

  • We are currently upgrading MFK. thanks! -neo
Tell him to do more Of a water change. It doesn’t do anything. He needs to use water conditioner. Did he clean the whole filter?
Yes he cleaned the whole filter, and he won’t do more of a water change unfortunately because he thinks he’s right in this situation. He’s pretty hard to deal with regarding issues with his fish keeping. He did put the conditioner in though.

A tank with large fish like that needs more frequent water changes than every two weeks. I have a moderately stocked 150 gallon and I change 75% every 3 to 4 days.
I will see if he will teach me to do it since I have more time than he does for maintenance of the tanks
 
I would advise against doing over 50 percent water change. Too much new water can kill the fish since they look to be in critical condition. Split it up to 2 25% water changes so there's not much stress put on the fish. Also you don't have to get into the hassle of convincing your dad. If I were you I would do this:

Day1: 25% Water Change
Day2: 25% Water Change
Day3: monitor condition
Day4: 25% Water Change
Day5: 25% Water Change

repeat until cured

So nothing else? I feel like they would need medication also
