So my Betta, Bo, has not been normal for 4 or 5 days now. He was not eating and staying at the bottom of the tank. I'm not sure exactly what is wrong but we treated his water with sea salt the last three days and he was doing much better yesterday, swimming at the top and eating. Today, a little more lethargic. Yesterday I kept the filter off because I thought it might be hindering his ability to swim. Today, I had it on most of the day. Some specifics, A one gallon tank which I plan to switch to a 2.5 gallon. I have a heater set at 78 degrees.
My first question is does the filter, which is a carbon filter, reduce the effectiveness of the sea salt? Second, I'm thinking we give him some medicine that covers a wide variety of possible diseases. What is the best stuff and three, if we give him medicine, again, should we keep the filter off?
Thank you and hopefully Bo thanks you.
