About a 10 days ago, shortly after I added a new plant, he started acting a bit odd, biting the bubbles at the top of the tank.
As the week progressed he started sitting at the bottom of the filter so I started watching him closely.
He then became lethargic and laying at the bottom of the tank, not moving. I noticed that he had quite a bit of rotting food at the bottom of the tank, I decided to do a 50-60% water change. I added 'Goldfish Tonic' as I didn't know what was wrong with him.
He then got white cotton-like orb things attached to his sides *see photos
They then started coming off of him once I did a 50% water change and added some 'General Tonic' and 'StressZyme' to his water.
I went and got Aquarium Salt and Methalyne Blue and added those the tank. For 2-3 days he started improving so put him in the 50 litre main tank. He deteriorated fast. Most of his tail is gone now, and it appears the orbs on his sides are coming back. He also has stringy bits hanging from him - I thought it was just poo but could it be a parasite?
So, another 50% water change in the hospital tank with Methyline Blue, Goldfish Tonic, Salt and a few food flakes and 2 sinking pellets.
He isn't moving much and looks so dreadful. I am worried he won't make it through the night.
I have switched off the air pump and carbon filter completely - am I right in doing so?
I spoke about this on another forum and was told to put him down. This horrified me.
I have added some photos.
Any help and advice would be greatly appreciated.
