Colubrids were extremely popular back in the 90s and early 2ks. They still are one of the big three.
Hognoses are the one that I'm actually amused with. The popularity on them is moving ahead EXTREMELY rapidly.
I have to agree on the colors and patterns being what drew my eye.. And it only became more interesting to me over time with all the new morphs.
My first Royal Python is my oldest boy. A normal/wild phase that I bought as a teenager for 20$ in 2000. Which amusingly became banned in my hometown later that year
The ease of care (minus the food strikes) and the manageable size is what still does it for me now. Cagesize is another consideration. They don't need a lot of space to be comfortable. They're pretty laid back and not as active as some species.
I love the look of some of the reticulated pythons now, but the size not manageable to me, especially when I have a back injury that I don't like to stress out. I don't have other people as comfortable handling snakes in my household so having a second body to help manage also isn't really a thing for me. I also wouldn't want to keep a retic in a similar setup as my Beeps. Sure, a lot of breeders still keep them in racks, but with a larger snake that is also a little more prone to climb trees in the wild, I wouldn't want to do that.
Eventually one day I would want to do a nice display cage with a small group of garters or a single kingsnake or Viet. Beauty.... but that's far off when I am not living with roomies. hahah.
