I think an combination of overfeeding on my part and an overindulgence in my pleco's algae wafer on my betta's part has given him a constipation/swim bladder issue.
Tuesday night I thought he was swimming a little strangely, but everytime I tried to really study his swimming patterns he would swim around as normal.
Wednesday night he seemed "stuck" at the top of the tank.
He wasn't rolled on his side or anything, but he had to work real hard to swim down, and when he stopped swimming he would float back toward the top of the tank.
I put him in a 2 gallon hospital tank with 2 teaspoons of aquarium salts at 82 degrees and he's been in there for about 24 hours now, but no bowel movement on his part.
He's either hanging out at the top of the tank looking very listless and unhappy, or wedged under the heater at the bottom of the tank.
I read that daphnia will act as a laxative for bettas, but all of my Local stores don't carry any, there's one more place for me to try over by my work tomorrow.
What else can I do to help my little guy?
