I think my betta has ich, he has been lethargic for a few days but I just noticed white spots on him today. Today I did a routine water change and added aquarium salt afterwards. He is in a ten gallon tank. I did have two ottocats but I noticed them both dead yesterday and removed them so he is now alone in the tank. I got one of them maybe a week ago so I assumed that he killed them both as he is pretty aggressive, but maybe the one introduced the ich to the tank? I was reading a few different ways to get rid of it, one being to turn the temperature up in the tank to 82°, I had it at 79° so I will slowly turn it up to 82° today and continue to add aquarium salt daily. He has spent most of the day laying on the bottom. I do have 3 live plants in the tank. Is there anything else I should do to help or speed up the process? Should I take the plants out? I am hesitant to add any medicines as I know many of them have negative effects.
