i have a 90gal tank with 3 clowns, 1 stripe damsel and one yellow & blue tang. all of them have ick (maybe not the damsel, but its hard to tell).. i used mardel coppersafe a couple days ago and the white spots went away for a day but when i woke up this morning to check on them, they all have white spots on them. .. i don't have a quarantine tank set up at the moment. what other products do you recommend? .. medication? .. i'm thinking about getting a UV
sterilizer once the ick is gone. .. the fish seem too look florescent when i shine a flash light into the tank to check up on them when the lights are off. is that due to the medication?
