Great article Cory. Dang it... my scheme to make my millions breeding guppies has been exposed! It is cool to see something written from an "insider" view. Seems I keep coming back to a few favorites, and depending on the LFS environment will keep a tank or two of "trade fodder" to support my habit ( heh). Killies and dwarf cichlids , in my experience are the best for that. For me they are interesting enough to keep for multiple generations, and not too labor intensive most of the time. Guppies are great..( I have a tank full too) but growing out those darn tails on the males... If you have a decent pair of apistos and good baby brine shrimp pipette delivery skillz you can go a long way. I would expect the same is true for Rift lake fish; although I have no idea what the nb fry eat.
Oooh, there is a whole other topic about letting a hobby turn into something-for-profit.
Wolfkeeper has an interesting point. For my part, I try and find the best phenotype (looks) and genotype (genetics) that is rationally available for my budget, and see what happens. I enjoy coaxing the fish I am keeping to breed, because what it says is that they are healthy and comfortable enough shift back to what they do in the wild... sigh.. or maybe they are just so stressed that they are driven to spawn before they die as a last ditch effort to save themselves and their species.
