I have been reading every website and every post I could possibly find to match symptoms of other bettas to my poor George and either none of the treatments are working or nothing is matching just right. So this is my last hope, as he looks like he is suffering immensely.
Almost a week ago I realized he wasn't eating when I fed my fish, he was swimming around and his usual self but just not eating. After two days I realized he didn't eat a thing and he stopped swimming around. I immediately removed him from the 10gal community aquarium and placed him into a 5gal alone with nothing to monitor him more closely. I fed him, nothing, removed the food. Decided to try fasting him, he is on his fourth day of a fast and will be trying a pea (he does not look bloated). Today was also his third day receiving an ES bath in a gallon of water for 20 minutes. The first time he was placed into the bath he swam around happy for a few minutes. Then back to not moving.
He was originally staying at the top of the water, not moving just lifting his head from time to time to breathe. He started staying at the bottom of the tank for the last day or so.
So on top of him not eating, not really moving, his one eye appears to be swollen , and one of the first things we noticed was VERY slight fin rot, so he has been medicated with Melafix for about a week now. Nothing has seemed to progress but nothing is getting better.
Today we thought maybe he is depressed and needs to be back with the other fish so we put him back in the 10gal and he is just laying at the top of the water on a plant, not moving. I attached a picture of him doing so. I just don't know exactly what to do. If he needs a different type of medication or whatever, it just is not clear with diagnosing him because of the range of symptoms he seems to have. Any help is really welcome.
