I've had my little guy Axel for about a year and a half now. For the most part, he's been happy and healthy. I moved him across town a while ago and he contracted a bit of fin rot, but I took care of it with some aquarium salt, Maracyn and Maracyn Two and his fins have healed.
Now, it's been about 6 months since the move, but I came downstairs to find him lying on the bottom of the tank with his spine contorted into an S shape. He didn't really seem to be able to move much.
I pulled out a small breeder tank that floats in the main tank, removed the plastic insert, and very gently scooped him into that with my hand so he wouldn't have to swim far to reach the surface.
After doing some Internet hunting I found that both Swim Bladder Disease and, oddly, tuberculosis cause a twisted spine. I'm pretty sure it's SBD, but I wanted some help on making sure that's it and what exactly to do with this.
Here's the form:
What size is your tank? 5 gallons
What temperature is your tank? 78 degrees F
Does your tank have a filter? Yes
Does your tank have an air stone or other type of aeration? Yes
Is your tank heated? Yes
What tank mates does your betta fish live with? None
What type of food do you feed your betta fish? Hikari Betta Bio-Gold pellets
How often do you feed your betta fish? 2 pellets daily, skipping once per week
How often do you perform a water change? Weekly
What percentage of the water do you change when you perform a water change? 20-25%
What type of additives do you add to the water when you perform a water change? Mostly just the tap water treater. I use the API brand. Very infrequently I'll add a very small amount of KH/GH booster and aquarium salt if I see the pH and hardness beginning to waver.
Have you tested your water? If so, what are the following parameters?
