Symptoms and Treatment
How has your betta fish's appearance changed?
pigment loss in Sept'11, suspected marbling
How has your betta fish's behavior changed?
She has been staying on bottom of her bowl/tank for the past 10 days. It seems like her tail sinks when she tries to rest and when she is trying to swim. I usually find her on the bottom in a vertical position. I also noticed a buldge on her right side two months ago (the blue arrows in the last 2 photos point to the buldge). I think it is in the area of her swim bladder, but she had no obvious trouble swimming until this past week - and the buldge is actually LESS noticable now. I searched this board a month ago and found a similar photo of another betta with a similar buldge and no one seemed to think it was a problem - that fish was also acting fine at the time. But now that she is having trouble swimming, even though the buldge is less noticable, I wonder if it has something to do with her problem.
When did you start noticing the symptoms?
10 days ago the trouble swimming started, 2 months ago I noticed the buldge, and 3 months ago she had a dramatic color change
Have you started treating your fish?
yes
If so, how?
I fasted her for 5-7 days (poor girl) and removed half of the water from the bowl to make it lower. 4 days ago I bought a 5.5 gallon tank and put in only 2 gallons to make it even lower, but with more water. I also bought a new heater and now the tank is staying 76 rather than 72 like it was with the old heater in the old bowl.
Does your fish have any history of being ill?
constipation one time a year ago
How old is your fish (approximately)?
We got her for 1.5 years ago, so ~ 2 years old?
Here are some photos of her resting and trying to swim, a before/after of her dramatic color change that happened in September, and some pictures of the buldge she has had on her right side for the past 2 months.
Should I try the epsom salt treatment? Do I just put that in her tank and leave her in it for a day or two? Will the epsom salt be uncomfortable for her? Should I feed her or not or feed something different? When the long fast wasn't helping I decided to feed her on Saturday and Sunday. I was kind of surprised she ate because she looks so pathetic on the bottom of her tank all the time. She had to work a little to get the food, but she seemed glad to eat. Anything else I should try? Thanks!
