So my betta Kala has been eating very little and acting lethargic for about 2 weeks. Last night, I noticed that he had a swollen red eye. I discovered from other posts on here that this is popeye. He also had some whitish gunk on his head and mouth near that eye. I didn't notice any on his body. I changed the water immediately and got him erythromycin.
Wednesday, the eye looked slightly more swollen, but the white stuff was worse...his head also looks like it might be pulling apart a bit, like perhaps there is an open sore. And it started showing up just slightly on his body, near the anal fin. I added the heater and epsom salt, did another 100% water change, and continued with the erythromycin.
Thursday morning is when I'm making this post... he looked the same as last night... until I came back home at 10AM to find that he has a chunk of skin/flesh hanging off of his head and it looks like his head is just rotting away!! What is this? Help!
If I do need to euthanize... I have no idea how to do that. Can someone point me in the right direction?
