HI I just joined this forum after reading a few posts to try and help my betta. I have a 5 gallon tank with a filter and water heater. My betta is a very active swimmer and all of a sudden we found her at the bottom of the tank looking a little bloated. When she swam she was nose down tail up and about 25 degrees and her body in a slight s shape. To try and fix this we first ran tests strips of the water. The only abnormality was the ammonia level is at .5. I have changed 40 percent of the water 4 times and each time applied the appropriate amount of stress coat to the tank. Today I went out and got Epsom salt and gave Lilly a salt bath for 8 minutes not sure if it should be longer. Wondering how to lower the ammonia level as it has stayed at .5 even after water changes and also if I should try something different with the Epsom salt bath.
