before you begin any treatment try to make sure it is ich and if so what is causing it. fish will recover much quicker if the actual cause of the ick is corrected. did you add any new fish lately that may have introduced the parasite? stress is also normally a cause for ich also. high nitrates, harassing fish or unstable water conditions will stress the fish out pretty bad, so making sure your water conditions are right and seperating fighting fish will give you a much better chance of beating the ick. what size tank do you have, how long has the tank been set up, what type fish do you have and what r your nitrate levels?
