Nicer than most fish?
Welcome to BP.net.
Before you get too far down the breeding road, I would suggest you purchase a BP or maybe two, and see how you do with husbandry and feeding and such. Once that's going well, you can start thinking about setting up a breeding project.
When you say you don't like rodents, is that going to cause you a problem when you have to handle them (dead or alive) for feeding. Just something to think about.
