Symptoms and Treatment
How has your betta fish's appearance changed?
his fins are no longer full, but almost look as if they are either clamped, or rotting. If rotting, it's a very strange, linear decomposition.. there is also whitish at the tips. I noticed this morning that he was covered with a thin white film as well, I could only see it when he was at the very surface of the water. I will try and upload a picture momentarily.
How has your betta fish's behavior changed?
lethargic, sometimes normal, sometimes spastic. Rubs himself on things sometimes when he swims, not sure if this is due to irritation or due to his newly decomposed fins and difficulty swimming. I bought him a little "fish hammock" so he switches between lying there at the surface of the water, and swimming around. Previously he was hiding in the eye of his spongebob ornament all day, but he is a bit more active now that he's back in the 5g.
When did you start noticing the symptoms? a week ago
Have you started treating your fish? If so, how?
I had him in a 2.5g hospital tank with AQ salts and betta revive. He spent most of his time hiding, and today I moved him into the tank with the corys again and he is MUCH happier. (There is a filter and heater in this tank). He is moving around way more. I have added maracyn 2 to this tank, as it is all that is available in my small town.
Does your fish have any history of being ill?
I bought him from a petstore where he was kept in a little vase. So probably.
I only noticed the thin white film today, as I previously thought that he was just "paler". What is this likely, fungal or bacterial? And what should I use to treat him? I really only have Walmart to pick from, as only one pet store carries fish here, and it has almost no stock. Also, as my corys are scaleless, I couldn't use certain Jungle products, and I think they are liekly contaminated so I would prefer to treat the whole tank.
