Hi all, Came back from a week vacation to find my daughters betta sluggish and with a small bulge in his left eye. I had him in a ten gallon with some tetras. The tetras are fine but I did a full water change and gave the Betta a salt bath in a small container (as per instructions I found online). He seemed to move around quite a bit more after the salt bath. I put him in a 1 gallon hospital tank and ordered medicine and a 5 watt heater. I'm using Sulfaplex. He now has it in both eyes but looks more active. How long should I wait until I dispose of him (which I'll then need advice on how to do properly/ humanely).
