It is customary to eat many fruits from trees on Tu B'Shvat and it's a Mitzvah to eat from every species so one can give praise and thanks to the Creator of the World who created all of these different fruits.
Those that follow the ways of the holy Ari have the custom of eating 15 types of fruits and at the very least, 12 types. Some say 30 different species should be eaten on Tu B'Shvat.
It is praiseworthy to include the seven species among the fruits.
