I tried to get a good shot of the belly in this.
I am not sure if the gills look okay. There is like a flap over them you can see in the video that I am not sure is normal.
This started a couple weeks ago where he would breath open mout, belly has gotten smaller and apetite seems to be reduced, but doesn't look like it is starving to me. It stopped chasing down the large TDO pellets it used to go nuts for about 2 weeks ago, and I rarely see it peck anything now.
I have prazi, but idk if I should assume a diagnosis yet.
