um... I'm a fantasy guy, so ya... Anyways. I don't know much animes that have tails... But Freezing, Sora no Otoshimono, Sekiei, Tayutama kiss on my deity I think are really good animes. So is Densetsu no Yuusha no Densetsu. So I think you should watch them. Only Tayutama has tails though, sorry man.
Freezing- Its ecchi but not Harem. But i'm sure you'll come to like it even though it doesn't have harem. Its one of those animes where the male character has extrodaniary that he doesn't even know he possess. Throughout the plot, his power becomes stronger and stronger. Its those rare powers...
Sora no Otoshimono- Angels, wings what so eva, but no tails... Ecchi and Harem. The plot surrounds this king of perverts boy.
Sekirei- Ecchi and Harem, its fantasy too. Its a great anime, but again, no tails.
Tayutama kiss on my deity- This one has tails... actually one tail. No ecchi and no harem.
These are just what I think you might enjoy:
Densetsu no Yuusha no Densetsu- this one is just funny...
Beelzebub- Funny XD!
Infinite Stratos- This one has Harem, quite a few. And interesting battles...
I like demon king daimaou (forgive atrocious spelling) or the Japanese way of saying it Ichiban Ushiro no Daimaou. The anime was pretty good for me, the manga is fine as well but they are quite different.
>>> Demon King Daimaou (Ichiban Ushiro no Daimaou)
Sekirei was a good one as well as others have pointed out.
