I just put my new hippo tang into my main tank last night after 3 weeks in QT. He immediately started swimming with my pair of clowns, which was quite entertaining! After the lights went out they separated, but today he's right back with them, and he's coming very close to my LTA as the clowns swim in and out of it, even brushing the edges of it. Is he in danger of being stung, or will he know better than to get too close? He really looks like he's tempted to follow the clowns right in! I hope I'm over-reacting...is there a reason to worry?
