Oscar not eating

My red oscar is acting really strange. I may be overreacting as this is my first oscar and I'm not 100% sure about their behaviors and such.

Anyway obviously as an oscar he/she eats normally like a pig and will greet me at the front of the tank and go nuts everything I enter the area.

However starting last night and continuing today my oscar hides from me when I get close to the tank and has refused to eat. The not eating part is scaring me because its an oscar and they will normally eat whenever they can.

The water parameters are not a problem i even double checked this morning. Its a 75 gallon tank with 2 red spotted severum tank mates. The severums never bother the oscar.

Edit: thought I would add the oscar is about 5.5 to 6 inches and the severums are maybe 4 inches

Just on a general note, if no specialized answers come in. Do a 1/4 water change and maybe keep him in a breeder box for a few days where you can monitor him closely and check his feeding habits. Sometimes there might be somehing stuck in his system so peas are like a laxative that could get things moving. Usually not eating is a sign of stress or sickness, thats why a general water change or solitary usually does the trick for any fish. Please however wait for advice from a specialised oscar owner

Thank you. I will keep an eye on the oscar and most likely do a water change once i get home. Hopefully that will help.

I have found doing the WC is a must with our fella. I really think water quality is of absolute importance especially when they are not themselves. Check your water values every day for a week. I would also do 30% WC every other day as well. The end goal is 100% healthy and prestine water for him.

Please keep us posted. Below is our boy Donald.

So I did a 50% water change with a thorough vacuuming of the sand and my oscar immediately sprung back to life and started begging for food.

It just doesn't make sense because the ammonia nitrite were at 0 at Nitrate were about 20 to 40 ppm. Not too high. And I also did a 50% water change on wendesday so it was only 3 days. There was a lot of poop in in some spots so maybe it was just poor water quality without actual signs of ammonia, ? Is that a thing ?

He may be a tad more sensitive to nitrates than usual.
