Hi. We have a younger Purple Tang and White Tail Tang that we introduced to our tank at the same time about a month and a half ago. The Purple Tang is tank bred. They are hanging out together all day and even sleeping next to each other at night. They are very cool to watch and the way they get along is much better than I hoped. Is it possible that they will continue like this, particularly as the Purple Tang gets older? I’m really just curious and wondering if this is pretty common.
