I have B. neuwiedi bolivianus and find them to be very aggressive feeders(more so than B. asper). I keep them pretty much the same, though I don't mist the neuwiedi as much(I've found that too much humidity in the substrate for baby Bothrops will lead to a bacterial infection in the eye and eventually kill them...so I tend to keep them all on newspaper for the first year. BUT I keep neuwiedi a little drier. I mist them once a week, and once when they're opaque and once a day after they clear up. Aside from that...keep them in a shoebox(if they're small), on newspaper. I replace the newspaper weekly.
Unlike venezuelensis, which are usually lizard feeders at birth, neuwiedi should take pinks. If not, tease them with an anole....but you probably won't have too. Mine don't run as much as baby aspers....they seem to have a little bit of a prehensile tail(but not as much as venezuelensis). They like to hang on to the hook.
