Personally, I wouldn't because it may adversely affect anything without scales. Here is what I do......I have a 2 gallon "hospital" tank to use, when my Bettas are sick. I fill it with very clean, ph balanced water, put a heater in it but not a filter, and I put my Betta in it, with the medicine. Betta Fix is to be used for 7 days straight, and do a water change after the 7 days. Once he's better, you can move him back to his original tank, without affecting the other creatures.
