Well I should know better, something bad happens to 90% of the fish I buy. I got a whte cheek tang and a gold stirpe maroon clown 2 weeks agao as part of my graduation present. I have them in a 10g Q tank for 15 days, they were eating and seemed incredibly healthy. So last night I decided to put them in my main tank a week or so early. When I woke up my white cheek tang was covered in ick and the marron clown had about 5 spots. Guess it's off to the hopsital tank and leave the main tank fishless for another 4 weeks
