My betas live happily with many other fish I have one in my discus tank with a bunch of discus and Cory cats and tetras and even a loach I have another Betta living with my Angels and a bunch of other Tetras. I find they play nice with most other fish. As far as the ich goes only one spot doesn't mean it's not ich it can start as one little dot then it will get bigger then fall off. After that it floats around a little till it lands In your substrate. Once this happens it grows for a few day then explodes and that one little white dot will have become hundreds if not thousands of little white dots and then will reattach itself to the host ( your fish) ich usually gets worse before it gets better
