Have you started treating your fish? If so, how? moved him to a small critter keeper thing so he doesn't have far to go for air, and so I can treat him. I put one teaspoon of epsom salt in on gallon of water and am using that. I also gave him some green pea, he has not eaten it yet, but maybe he will, and I will check later when I change the water.

I am treating him for constipation

, which, apparently is a common ailment with bettas. Unfortunately, I did not think about this until he was ailing for a few days. I started treating him on Friday, 5/6/11. He was symptomatic at the beginning of the week.
Am I using the right amount of epsom salt? I thought I read about using a tablespoon, I am using a teaspoon.
Anything else I should be doing?
Does anyone know how to warm up small container?
Thank you!
