I had ich problem to my fish during start of my tank.. I fed Dr. Bassleer garlic pellets regularly and added some garlic juice too in pellets, introduced doctor wrasse, it Helped a bit removing the unwanted parasites and survived in my tank for almost a year and one fine day got stuck in wavemaker. Other thing I did was kept water temp at 26.5-27.5 for almost few months with LPS. Water changes 15% every 10 days to 2 weeks None of the fish died of ich.. and never got any ich. Some times it’s better to start over, quarantine ur fish. Now I have different kind of cleaner wrasse for almost a year, got it as baby 1/2 inch, always stays inside rocks or gazes on glass.. unlike doctor wrasse who moves all over the tank and does home service .. lol....this has its own SPA.. everyday morning most of the fish go to it’s location to get cleaned.. lol ...very interesting to see.
