Symptoms and Treatment
How has your betta fish's appearance changed?
His top fin is nearly gone. I don't know if it's finrot and preventing him from swimming correctly, or if it just got torn off somewhere and is influencing his swim. His back fin isn't very big and flowy, either, but it never was HUGE like some bettas. He isn't a crowntail or a female, so it was never really a problem, but now I think he may have something like fin rot or a bacterial infection.
How has your betta fish's behavior changed?
It hasn't, really. He swims to the top for air, when I come in the room he perks up, and he still attacks his food with just as much excitement as usual. :) Sometimes he lays on his sides on the bottom of the tank, though, which makes me really nervous. Is that unusual?
Lately, though, I've noticed he's had a little bit of trouble swimming, but it's barely noticeable. He's been floating more sideways, (like vertical, I guess) and he lays at the bottom on his rocks sometimes (but that's not unusual for Vasco). He's very prone to bloating, so I'm used to it. I've cut his food intake down a lot.
When did you start noticing the symptoms?
About a week or two ago...I didn't think anything of it really, until I started reading into these types of forums and questions. I had assumed he tore something on a plastic plant, so I removed the plant and didn't think anything of it.
Have you started treating your fish? If so, how?
Right now, Vasco is in a hospital tank (a .5-Gallon cube) with about a half to three-fourths of a teaspoon of aquarium salt. I did a 100% water change and plan to wash out and dry his current tank (a one-gallon cylindrical vase - I'm switching him over to a one-gallon goldfish bowl after our move up to college). I'm getting him a heater today and an air rock.
Does your fish have any history of being ill?
Not that I'm aware of. He occasionally suffers from bloating but I've recently begun fasting him on Saturdays and feeding him half of a pea on Sundays to relieve the constipation. It seems to be working better.
How old is your fish (approximately)?
I purchased Vasco form a local Critter Corner pet store a little bit less than one year ago. Probably...last October, so about nine or ten months ago.
You can kind of see where the tears and things are on his bottom fins and tail. His tail looks normal to me, though. Like, not really much different than usual. Also notice how the top fin seems to be almost missing. There's like, a nub left. It's not like, black and red like everyone says fin rot should be. It's like...white and stringy, you know?
Sometimes he kind of just lays on the bottom like this. He swims around and stuff though too! I mean, he's very active, but when he just lays like this it makes me nervous that maybe he has a condition that I don't know about or that he's sick. Right now he's laying on his leaf hammock though. :) <3
