Have you started a thread for this yet? If so I'd like to answer this in an open thread. If not, let me please tell you that those are some very harsh meds for a betta. It would help if you could get a clear close up picture of your fish and post it in an open thread so I can take a look. I would like to be sure it is actually ich you are dealing with before I make medication suggestions. If you could just post me a link here once you get the pic(s) into a thread I will be more than happy to help you.
I was reading your contributions to the Ich FAQs. I don't know what to treat my male betta with. He's in a 1 gallon fish bowl. We got him 2 weeks ago. We've done about a 30% water change twice, spaced 1 week apart. He had a three day course treatment with "Betta revive" and Kosher salt for a fuzzy white growth on his ventral fin which is now gone. Today was the first day we noticed the white spots. I feed him a couple pellets of Betta food every 2-3 days. At the aquarium store, the person sold me a medication that has formalin and zinc free malachite green in it. Other meds seemed to just have malachite green in it. The "betta revive" we used earlier for his fuzzy white spot also had malachite green and methylene blue in it, but obviously it didn't prevent him from getting Ich. Any suggestions on what I should actually use?
