Hi, I've never posted here before but I'm hoping I can get some help from betta experts. I'm just gonna fill out the info sticky.
What size is your tank? He is currently in a 10 gallon community. When these symptoms started he was housed in a heated, unfiltered 1 gallon bowl with regularly high ammonia.

Symptoms and Treatment
How has your betta fish's appearance changed? I have had my betta Ghost since November. He is a cellophane double tail and when I got him his tail and fins were almost completely see through and nicely rounded. Over the last 3-4 months I have been noticing a very slow deterioration of my little guy's tail. It began by getting steadily darker (brown and black). The edges are getting ragged and the bottom of the bottom tail is black and wrinkled looking. The black/brown goes almost all the way to his body. The end of his body where his tail is has also been bloodshot on the top and just today I noticed that the area that is bloodshot has gotten much redder and spread to the bottom of his body as well. I attached a picture from about a month ago - the more recent ones are on my phone - but hopefully you can kind of see the brown on his tail and the black mess at the bottom. I'll try to get more pictures on here.
How has your betta fish's behavior changed? I haven't noticed any change.
When did you start noticing the symptoms
? Early February
Have you started treating your fish? If so, how? I tried a ten day salt treatment in his old bowl but it really just stressed him out and there wasn't any change.
Does your fish have any history of being ill? No
How old is your fish (approximately)? 6 months or more
Please help I don't know what to do for him this doesn't match anything I've found online.
