The quinceañera is not a Catholic tradition inasmuch as it is not a tradition of the Church and is not practiced everywhere that Catholics are present. The people who do celebrate the quinceañera, however, tend to be Catholic, as this is a Mexican tradition and Mexico is a mostly Catholic nation.
You can't eat meat on Good Friday, but you only eat fish instead. But some say This is the kind of nonsense that makes Protestants laugh at Catholics. The Bible CLEARLY says that we are free to fast or not fast, eat meat or not eat meat, as we please. IT CLEARLY says that these kinds of "religious practices" are worthless and that God sees "good works" as nothing but "filthy rags." Follow Jesus. Give Him your heart. That's all that counts. These kinds of questions reflect the kind of dead useless "religiosity" that Jesus came to ABOLISH!
Apostolic Tradition means that the Teachings of the Church can be traced all the way back to the Apostles.
Yes, you can. The only days Catholics don’t eat meat are Good Friday, Ash Wednesday and the Fridays in the Lent season. It is therefore imperative to state that Catholics can eat meat during Holy Week. Having said this, there are still some Catholics who do not adhere to this. (this was my dear friend googles answer)
Roman Catholics may not eat meat during a day of fast (Ash Wednesday, the Fridays of Lent, etc.) Otherwise, Catholics have no dietary restrictions.
Many Catholic beliefs and practices are not found in scripture so to justify these they put tradition before the scriptures
The current post-Vatican II regulation is that Catholics must not eat for one hour before receiving Holy Communion. Traditional Catholics do not eat for three hours.

The catholics belive that eating red meat on Friday is a sin or disgrace and so the only meat they can eat is fish, that is not poultry or red meat. The above doesn't address the history of this tradition, which has nothing to do with piety. See links
In the pre-Vatican II tradition, Christmas Eve was a fast day up until First Vespers of Christmas in the evening, unless it fell on a Sunday. In the current tradition, meat is permissible on Christmas Eve; but if it falls on a Friday, abstinence from meat is required until First Vespers of Christmas in the evening (unless dispensed of by the Bishops of your country, as is the case in Australia, the United States and a number of others).
It goes with the Jewish tradition that the day ends at sundown.
Catholics have no prohibitions on what they can eat.
