Hikaru's hair (if you are standing behind them) is going to the left and, Karou's hair is going to the right. If I'm wrong it's the other way around.
Hope this helps!

The twins of Ouran High school host club? Their names are Hikaru and Koaru Hiitachin
The beach, The sun , The host club . and Haruhi and Hikaru's first date
Hikaru Hitachiin is a character on the manga series, Ouran High School Host Club. His love interest is Haruhi, however, his love is unrequited.
Kaoru and Hikaru's hometown host club, the Ouran High School Host Club, is located in the prestigious Ouran Academy in Japan. The club is situated in a luxurious building on the school's campus, where the twins, along with other members, entertain female clients. It is known for its opulent setting and the unique personalities of its hosts. The story primarily unfolds within the club and the surrounding areas of the school.
He confessed in chapter 63, but Haruhi rejected him some time later on.
hikaru is a twin in ouran high school host club. the other twin that is hikaru brother is kaoru. the host name of the twins is little devil because in episode 5 they wanted to go to haruhi's house but she said no so they made a trick.
Well Hikaru has more of a clear voice and a little more high pitch then Kaoru's. Kaoru has more of a nazley voice and just a little deeper then Hikaru (at times but sometimes Hikaru is depper) . And plus Kaoru is sometimes more of a nicer person then Hikaru (when they are out of middle school) and that's how i tell the difference hope this helped :)
I think that was in "The Twins Fight" , which was episode five.
The blonde male in Ouran High School Host Club is Tamaki Suoh.
The leader is Tamaki, the v.p. is Kyoya, the tallest is Mori (Takashi), the smallest is Honey (Mitsukuni), the twins are Hikaru and Kaoru, and the girl is Haruhi.
Monica Rial plays Renge Houshakuji on Ouran High School Host Club.
If you mean her fear of lightning, Tamaki finds out in Episode 8 and Tamaki tells Hikaru in Episode 16, and I would think the rest of the club found out in Episode 16 too because Tamaki tells Hikaru while yelling at him over the phone with the rest of the club listening to him.
