I have had my betta for over 2 years, and he has always been very active and healthy. I had him in a 3 gallon tank and just moved him to a 5 gallon today. For the past few months he has been very lethargic and laying on the bottom of the tank on his side. It seems like he has trouble swimming, but he has still been eating a little bit. For lack of a better description, the main thing that looks wrong with him is his anus - it has turned black and looks like it is rotting. I added a little epsom salt (1/2 tsp) when I put him in the new tank today and am not sure what else I can do for him. I just don't have the heart to give up just yet. Any help will be greatly appreciated.
These are the best photos I can get right now.

Oh right, haha I guess in between anal/caudal fins would have been a better description. Anyway, yes, he's had the black for almost as long as he's been acting weird. I just added the salt today when I put him in his new tank. 1/2tsp to 5 gallons, so not very much. Something I just noticed - it almost looks like there are bones sticking out from the rot...is that possible? :(
Is it treatable? Is it contagious? Should I euthanize him? Poor guy, I feel so bad.
It does look like what happened to my poor Venom a year and a half ago :( The weird thing that happens to blue bettas. I have no advice, one of my girls looked like this and I euth'd her :( Even though I could have tried treatments, she was miserable and I couldn't let it go on any further. I'm so sorry this is happening, he's a beautiful boy!
I wish I could help more I just dont know, but AQ salt would be better right now instead of espom salt. Did he have any fin rot before this started ? It could be advanced fin rot that is now getting to his body. Good luck I think it is treatable with the AQ salt and extra clean water for now until someone else comes along that knows more what to do. I sure feel bad for you and him both, hang in there !!!
