I had my roommate babysit my betta this weekend, and when I got back Monday morning he was alternating between lying on the bottom of the tank and swimming erratically. I also noticed some very tiny white spots on his fins, and I believe by my research that he has ich. So other than never letting my roommate babysit ever again, what can I do? Living in a college town means I don't have much resources or money so I need a relatively simple fix. His spots are still very small so I think I have a chance of saving him.
