Have you tested your water?
Yes
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
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.
Yesterday I noticed that one of my plecos has ich and today another has a small white patch on it's back.
I've begun treatment with salt.

One of the plecos was sucking on the front glass and I noticed odd patches on its underside that I've never seen on any other fish before. I searched online but haven't found anything like this. There are what look like infected patches near the fins with raised bumps that appear to have crosses in them.

Hoping someone here can identify this and possibly offer a treatment solution.

Thank you in advance!
