Bless Him.
He does look in bad shape bless him.
It's not looking promising.
He might be struggling also with both meds in the tank so stop the tetracycline.
Do a water change and increase aeration.
I'm blind as a bat so can't see what athena seeing, but here some info for you.
Myxosporidiosis
Symptoms:
Fish exhibit numerous white cysts on the skin and gills. Cysts can become very large causing the skin overlying the gills to swell, which will prevent the fish from getting enough oxygen. Because this disease affects the gills, fish may be seen at the surface, acting like they can't get enough air. In severe infestations, the fish may bloat up, with tumor-like protrusions and eventually die.
Cause:
The myxosporidean parasite Henneguya.
Treatment:
This disease is fairly difficult to treat. Increased aeration in combination with merbromin baths is the only current method for treatment.
