Hi everyone! I have a very sick rescue betta that I got from a friend- was severely neglected, lived in an 1/2 gallon container that was never cleaned. He has severe fin rot and ammonia poisoning too- many betta owners have recommended methylene blue as a treatment option- but I didn't want to try to use it until today- until I was sure the fish was strong enough to survive the treatment. Could anyone give me instructions on how to use it? I have not used it in the past but I am willing to try anything to help my fish. I would prefer to start the treatment in a low dosage so I can see how my fish reacts to it and so that there is no risk of overdosage. Thank you so much for the help!
