Symptoms and Treatment
How has your betta fish's appearance changed? When I first got him (two weeks ago) he had a bit of black around the edge of his caudal fin, and it was lighter before the black on that same fin, and it was lighter on his anal fin. There was also a tiny hole in his anal fin. I thought it might be mild fin rot, so I kept an eye on it, but it did not progress, so I thought perhaps that was just how he was coloured. Yesterday, I noticed that his caudal fin has reduced in size by literally about 50%, and his anal fin is going down as well, and there's more black on his caudal fin. There's also another tiny hole on his cadual fin. I don't know how that happened without me noticing, but it seemed pretty sudden...
How has your betta fish's behavior changed? It hasn't, he's as happy as ever. :) Or as angry as ever, I suppose, he flares at me when I come near lol.
When did you start noticing the symptoms? I noticed when I first got him, but didn't think anything of it. I noticed that it was definitely fin rot yesterday.
Have you started treating your fish? If so, how? I did an 80% water change and cleaned some of the gravel. Yesterday, as soon as I noticed I added one teaspoon of aquarium salt... today after the water change, I added another teaspoon (I dissolved it in a small container of water first before adding it).
Does your fish have any history of being ill? Not that I know of.
How old is your fish (approximately)? I'm not sure. I purchased him two weeks ago from a pet store.
So, this is definitely fin rot, right? I've never had a fish with fin rot before, so I've never treated it before. I can provide (bad quality xD) pictures if needed.
Is the aquarium salt treatment the way to go? Anything else I can do? Will his fins grow back? How long should I treat him for? Thanks. :)
