Awesome fish. I got one and QT'd it and was eatting good. Then added to my DT and bam, my six-line started hitting it. I managed to catch him a few days later, but was really beat up. I moved him to QT, but wasn't eatting as good as before and only lasted a week. I didn't think anything about adding him, since I just had a yellow coris that the six-line never bothered. Just be careful if you've already got a six-line. Good luck, from the photos of them, they are awesome looking when they get older.
