Oscar with hole in the Head

I answered a similar question like this a couple of weeks ago. When my Tiger Oscar had HTH, I didn't use any meds whatsoever. I placed her in a hospital tank, did large water changes and fed her a variety of different foods. Within a week, the holes were almost closed and after 1 week and a few days, they were closed completely. I put her back into the 225 and she's been fine ever since. What's your water condition? Are you feeding your Oscar the same thing day in and day out?
 
I just don't get it! Today he's got a whole on the other side a little smaller than the one in the picture.. and some smaller ones forming in the side in the pictures. Water conditions have been perfect: ammonia/nitrite=0, nitrates 10ppm or below. I've been supplementing his HBH oscar grow with liquid vitamins. An occasional mealworm (once a week). I've treated with metronidazole (no carbon in filter), I've been using melafix.
On the plus side, he's still got a good appetite, and he is less pale in color.
 
Hang in there.. sometimes these things need to work themselves out.

if it was diet that caused issues there could be some residual fall out still

yes.. just like a human taking a multivitamin, the results may take a week or more to manifest in the extremities (ie. skin)
 
Well, I think that it's starting to get a little better. Is it really necessary to do a water change after a week if the nitrates are only 5 ppm? I did one anyways today..
