For me, it was fishkeeping first. I'm just now starting to get more involved in the herpkeeping world (even if I don't have any myself just yet). I've tended to be more interested in the cultivated varieties of fish, mostly fancy goldfish and bettas. I've kept all sorts of peaceful community fish, from tetras to livebearers, rasboras, plecos, ect. At one point I had three fantails, a blue oranda, bronze lionhead, tricolor demekin, panda demekin, and a pearlscale, and several bettas. I've also tried dabbling at aquascaping some of my smaller tanks.

I've paired it down lately to just three goldies and two bettas. My oldest and largest fantail, pigeon (5 years old at about 12cm), my two year old bronze ranchu (already almost as big as pigeon, and still growing ) and my baby panda (already losing the black, he's going to be a white one when he grows up) are permanent fixtures at my parents shop (and getting a brand new 50G tank, since their old one is, well, old). My two bettas, a bronze halfmoon plakat and a black/red butterfly delta currently share a 10G divided tank, but I may have to rehome them before I ship off to school.

I've always wanted to expand into saltwater, cichlids, puffers, and many oddball fish, and I probably will, but if I had to choose I would always keep fancy goldies (especially once I can have a pond) and bettas. Even if some other fishkeepers consider them 'lesser' fish.

I've always joked with my parents that that betta when I was a child was a gateway drug to cichlids, saltwater, lizards and snakes.
