Furan 2 and Triple Sulfa are available at fish stores but you may have to call around to see which ones have it in stock. Either one should work for you. For 20 gallons, you will need 2 boxes to get you through 10 days of treatment. It is approx $9 per box. I got mine at MOPS (mail order pet supplies in Hamilton) but I'm sure that you should find some closer to you. Use the full course of the treatment so it doesn't come back stronger than before. You probably won't see immediate results because there is tissue damage that must regrow but after treatment, keep them in quarantine (separate tank from all others) for at least 4-6 weeks to make sure nothing else crops up before you put them with the other fish.
Here are the directions for use that I got directly from Seahorse.org.
Furan 2 has directions for use with live food or not, whichever way is easiest for you.
