If you are serious about keeping Amazon Basin Emerald Tree Boas, then record keeping, that is recording every meal, every BM, shed, mating, etc. is essential.
Like many collectors, we keep an individual data sheet on each animal that follows them from "cradle to grave".
Failure to maintain a log on each individual animal can result in catastrophic double feedings or other incidents. It is just too difficult, even with one animal, to remember critical data.
