i'll try to cover what already hasn't been covered...
1. each BP should be housed separately.
2. BP's prefer to hide like 90% of the time; it's normal. if they're out, it will be mostly at dusk or night.
3. if they skip or refuse a meal, it's ok, don't freak out; sometimes they even go on extended food breaks.
4. when they go blue (into shed), increase humidity; do not bathe them, let them shed naturally first.
5. BP's can drink the same tap water u drink; and they're probably drinking when you're not watching.
