I have a male half moon betta fish named Archimedes. I have had him for maybe 4 months now (I'm not good at keeping track of the date). About a week ago, I had noticed his fins were a bit torn and started to turn a bit red in some areas. He had also started to get small white blobs on his body. He also started to get a little less active about a month after I had gotten him. I had been searching for diseases and illnesses that could occur in a betta, and I have my mind set on fin rot. I am pretty new to betta fish and I want to make sure I am doing the right thing here. I decided to pick up a bottle of API Betta Fix ( ). I unplugged his filter gave him about a teaspoon of betta fix yesterday and today (I realized his tank is smaller than I thought, so I am going to give him half a teaspoon tomorrow). I want to make sure I am doing the right thing for Archimedes here, and this was the only website that seemed helpful. If anyone could give me some info about this, that would be great. Also, I would like to know: - Does he really have fin rot or is it something else like ich? - Should I continue to give him betta fix and follow the instructions on the bottle? - Can betta fix harm him if he doesn't really have fin rot?
