So for anyone who was waiting on more info: I got to meet the breeder in person yesterday, and he's a wonderful guy. :) It's always a little strange meeting people who you've only ever talked to via email and know very little about, but luckily he was really great-- he's just a bit older than me (ie. just going into college), and he's been breeding for four years now. He showed me my girls and then showed me around his breeding room while he was getting them ready for travel, which was a lot of fun. (BABY FISH. Okay, as someone who's never actually seen a baby betta in person, much less HUNDREDS OF THEM, it was neat.)
Currently he's got two spawns that are still very very little-- one is under a month, and the other was just hatched last week. I don't know their colours, but they're both plakat spawns-- as they grow out he's going to keep me updated, and I'll in turn keep you all updated. The number of people who confirm they'd like to adopt will probably determine the number of culls he saves for me (and obviously I'm considering one or two of my own, buuut :)).
And for anyone who's interested in actually buying non-cull fish: he also introduced me to the parents of his next spawn, two absolutely STUNNING super-blue plakats. Seriously, these fish were amazing. (I might've actually drooled a bit). He won't be spawning them for a little while, but oh my god, believe me, if the parents are any indication he's going to be selling off some lookers.
