Symptoms and Treatment
How has your betta fish's appearance changed? His lower body is VERY thin. It's not where his stomach is, so it's not that he's hungry.
How has your betta fish's behavior changed? None
When did you start noticing the symptoms? He's my sister's fish, so when my mom and her partner went on a trip to Europe he stayed here while I went to my dad's house with my fish. She was never really at the house, so he didn't get fed. When I came back, he was thin. This was the 28th.
Have you started treating your fish? If so, how? No
Does your fish have any history of being ill? He gets bloated VERY easily. I swear, if you look at that fish wrong he won't poop for a week.
Also, when I came back he had fin rot (I believe from the ammonia) and white fungus on his face. He was also very gray. With daily water changes, his fins look much better and his fungus is almost entirely gone.
How old is your fish (approximately)? She's had him about a year, and got him from a pet store.
