So I was given a betta tonight I was told he is a beautiful black orchid twin or double tail. He is in wicked bad shape I have never seen a fish with such bad fin rot. It's so bad he has sore on him. I went picked EM erythromycin put out by API. I gave him a 15 min methylene blue dip. He is currently chilling in a cup before I put him in some medication in a gallon keeoke only so he doesn't have to work so hard to swim and stuff. He normally lives in a 5 gallon. I boil my almond leaves to make a strong tea for them. I put some in his water as well with a touch of salt. He seems extremely painful. I also have marineland Total Care conditioner in his water it helps with slI'm coat. Work's better than API in my opinion. I will post pictures of zant. Any help would be great. He dosdoes want to give up so I won't either.
