They are not difficult to care for at all you just need to keep decent humidity and provide a big enough space for them.

They are not agressive in general specificly if you get a young animal and handle it a lot as a baby. The venom is very similar to Atrox (Diamond Back Rattler) but they only carry about 10% of what is required to kill a human. Their delivery is also not very good at all. They are not considered a "venomous snake" under most law and no permits are required in most areas, etc.

If one is worried about envenomation cloth gloves and long sleeves are all that is needed for protection. They have no true fangs just enlarged rear teeth that make a wound that venom flows into. Hence with gloves and/or sleeves any venom will be absorbed by the material and not make it into the wound.

I have one and I handle him bare handed all but in the times I need to do work on his viv when he is in shed. He gets a bit testy when in blue but so do many snakes.

So yes the venom is potent but the volume is very small and the delivery is not sufficient to be very dangerous. I would not try to talk anyone with a bit of experience and an understanding of the space and basic caution needed not to get one. They are great snakes and most (not all) have great attitudes. They are very active during the day and don't hide much so that makes them great display animals too,
