Stress is the biggest cause of Ick , like I said before ,Tangs are notorious for getting it that way . I'm not 100% sure but I think it weakens their immune system some how . And Ick can be transmited very easily . Some fish (espacially silver or light colored fish) can be on ther verge of death before they even show symptons . I know Pleco's are like that . I lost almost an entire FW community tank that way before i finally got it under control . I tried everything and it took over 2 weeks . I lost over 25 fish out of about 40 in my 120 .Thats why I try to tell everyone to QT their new fish . Its real easy to set one up . All i have is a 10 gallon tank with a hang on back filter and nothing else in the tank. You can put some fake plants or some rocks in it so they feel a little safer but I wouldn't put any gravel in it , just somewhere for uneaten food to rot and foul the water. |
