Symptoms and Treatment
How has your betta fish's appearance changed?
He's been a little bloated, and around what I'm assuming is his anus there's a fleshy swelling. The swelling is white, and kind of looks cancerous. It looks like it came out of his anus.
How has your betta fish's behavior changed?
The funny thing is that he's totally normal and active.
When did you start noticing the symptoms?
I first noticed the symptoms today.
Have you started treating your fish? If so, how?
I haven't treated him because I have absolutely no clue what it is.
Does your fish have any history of being ill?
No, but I've only had him for a short time.
How old is your fish (approximately)?
Judging by his fins, I'd put him at a year or a year and a half. I've had him since about April.
I just want to add that he's a regular veil-tail, but extremely large, plakat size almost.
