Porcupine puffer maybe sick??

[JCupcakes]

Trying to see what's going on with my porcupine puffer. For some background, it was born with one eye so it's a bit of an outcast to begin with. It was happy and healthy for several months but then developed some kind of bacterial infection. I treated him for a couple of weeks and the infection seemed to clear up, but now there's a bright yellow spot that appeared on it's back and it's spending a lot of time at the bottom of the tank and not swimming around much. It still seems to be eating but not enthusiastically. Water levels all seem good, all the other fish in the tank seem happy and healthy.

To assist, will need a pic or two, and even video using bright white light intensity, no blue to clearly see what you are describing
