Symptoms and Treatment
How has your betta fish's appearance changed?
(sorry about the algae; i've been bad about the lights this week)
she has this strange bump under her mouth/chin. it appeared out of seemingly nowhere. it doesn't seem to be hindering her, though. she eats and swims just fine.
How has your betta fish's behavior changed?
she's started clamping her fins which is unheard of behavior for her.
When did you start noticing the symptoms?
two days ago.
Have you started treating your fish? If so, how?
I did a 50% water change and bumped the temperature up.
Does your fish have any history of being ill?
not at all.
How old is your fish (approximately)?
i got her in mid march of this year. i thought she was really young when i bought her, but as it turns out, she's full grown. she's just small.
So, does anyone have any idea what's going on? I've done a little research and I've seen answers that range from bacterial infection to tumor and I'd like to know what I'm up against. Thanks in advance!
My male betta had the same thing recently. No one on here would answer me about what it could be, but eventually I figured out it could be a tumor... but then it disappeared a week later, so I have no idea what it was.
There is a condition called Lymphocystis, which causes pimple-like growths.
Lymphocystis is caused by a virus, and is a common viral aquatic disease. It's usually self-limiting, meaning that the fish's immune system can fight it off within several weeks or months. (Feed a quality diet, reduce stress, keep the water clean and warm.)
Here are two photos of fish that have the condition, followed by links for more information:
I've looked into lymphocytosis as well, but it doesn't really match up. This looks more like rounded pimple rather than a textured bump. It's totally possible that it's just in the early stages, though.
In any case, I guess that only thing I can do is wait it out. Thanks everyone!
