My fish Mystic has had some persistent fin rot over the last 3 weeks. I contained it with aquarium salt and that halted any further damage. I took him off of it thinking that his fins just had some damage done as they were not melting or blackened anymore.
Well over the last week his fins had gotten worst and his behavior more and more lethargic as the days went. I ordered Maracyn Plus and after 24 hours of being in medicated water his fins have regained color and lost the melting look at the edges. He also has pepped back up and swimming at the top of the water column again. I'm hoping to have a happy healthy fish at the end of this round.
One question though in a 2.5 gallon hospital tank do I change the water on each treatment day or do I keep the same water and dose?
