Mitchell Posted April 28, 2011 Share Posted April 28, 2011 So today I noticed my yellow tang scratching on the sand and after looking closely at him he has black ich all over him. He has always had a couple dots since I got him 6 months ago, but this is by far the worst he has had it. I'm not too worried, because its a hardy fish and black ich isn't that bad and it should fall of in about a week. My question is what could have caused it to get so bad? I added a hawkfish april 1st and all the other fish I have had since I started the tank 6 months ago. Sent from my DROIDX using Tapatalk Link to comment Share on other sites More sharing options...

Mitchell Posted April 28, 2011 Author Share Posted April 28, 2011 when was your last WT? maybe something was off... temp, nutrients etc. Do you mean waterchange? If so I did one 4 days ago. I did turn my heater down 3 degrees. Sent from my DROIDX using Tapatalk Link to comment Share on other sites More sharing options...
