Here are some answers:
What size is the tank? (anything less than one gallon is too small. a good way to measure it is see how many one gallon jugs, like a milk jug, it holds)
I know it is insufficient, but he is in a 1/2 gallon tank.
What is the temperature?
Water is kept at room temperature. Don't have a thermometer (again, I know, bad fish parenting) but probably around 72.
What is the food schedule?
Once a day, daughter fees about 5 pellets.
What is the food type/brand?
Aqueon Betta Food (pellets)
What was the water change schedule before he got ill?
I changed the water every weekend.
How much did you change?
Since he showed signs of tearing, I've kept a jug of conditioned water (to get it too room temperature). I scoop out about 1/2 of the water and pour in more each day.
Do you add any conditioner or dechlorinator to the water?
Yes, originally I used a conditioner that came with his bowl. I ran out and started using Aqueon or Tetra at about the time I noticed the tear.
Do you use tap water?
Yes, conditioned and brought to room temperature by sitting around.
Any other symptoms? (loss of activity, lethargy, color change, etc)
He doesn't seem as active to me as he used to be, but maybe I'm imagining it. I don't see any color change or notice any black on his fins. They are just shriveled and falling apart.
