I've killed many A. versicolor slings in the past... :blush:
However, I haven't lost one since. VENTILATION is the golden threat you must follow to raise these beauties. A Deli-cup with no ventilation holes is a death sentence for them... I have tried many different methods. Very high humidity will not kill them, IF there is sufficient ventilation holes - been there done that. High humidity in an enclosed deli-cup, with insufficient ventilation holes WILL kill them - Fungi will grow in their booklungs long before you realize it - been there, done that... Again!
The method I have found to be successful is to create as many ventilation holes as possible. I aggree, I might overdo it, but I haven't lost another versi yet. :whistle: (Touch wood!). My deli-cups, where I raise versi's in, look like it have been in a "needle-machine gun" war! Keep the humidity high and the temperature slightly raised above room temperature.
I have found that my versi's (slings) do better with pre-killed crickets... Why? I don't know. One of my adult females, which I raised from a 1cm-sized sling, won't catch alive pray even to today. She is a proper hand reared tarantula! She will only takes a cricket from a tweezer, very gently. She is a real lady. :lol: My other versi's have grown out of that habbit, tackling their pray down!
I wish you all of the best with your versicolor baby... If the situation takes a turn for the worst, please don't loose heart. It is a difficult species to raise, and sometimes it feels like they drop you for no apparent reason.
I'm somewhere in the future, and I look much better than I look right now!
