Any idea what’s wrong with my Geophagus Winemilleri (or Sveni, I can’t tell them apart)

Have you tested your water?

Yes

If yes, what is your ammonia?

0

If yes, what is your nitrite?

0

If yes, what is your nitrate?

Looks like 0, but I’m not sure. Might be 0.1-0.2

If I did not test my water...

1. ...I recognize that I will likely be asked to do a test, and that water tests are critical for solving freshwater health problems.

Do you do water changes?

Yes

What percentage of water do you change?

21-30%

How frequently do you change your water?

Every week

If I do not change my water...

1. ...I recognize that I will likely be recommended to do a water change, and water changes are critical for preventing future freshwater health problems.

It reminds me of lymphocystis. Would monitor for any changes. Viral in nature and no treatment. Keep water clean and make sure fish is eating.

Difficult to tell, but when I blew the pic up I agree, looks like it might be lympho.
