Eeeek sorry dude. I've been getting extra hours at work so have been a bit busier than I thought I would be.
The SOTM i sent you is good on general care.
This is how I keep mine as adults......
They are kept individually in clear plastic boxes measuring roughly 20cmx10cm. The substrate is around 2cm of coco fibre and sand (60/40 ish) and is kept dry. Hides are two pieces of oak bark, one stacked on top of the other. I provide a bottle cap for a waterdish and this is always kept full. I also spray the enclosure lightly every 5days to a week. I don't use any additional heating and temps in the room range from 12c - 25c+. They are fed 1 to 2 appropriately sized crickets every 7 to 10 days.
I'm pretty sure there's some pics of their enclosures on here somewhere, but I'll try and get some more up when I've got time.
This is my first time raising slings of this species and I'm undecided as to whether I'm going to raise them in groups or not. I've had reasonable success doing this with my E. flavicaudis, however my E. alpha have been very cannabilistic. I guess a trial is in order lol.
As for conditions to raise the slings, the substrate will be the same as mentioned above. Hides of oak bark will be provided. To provide moisture I will very lightly spray the enclosure twice a week and also keep a small area of the substrate damp to avoid the risk of dessication. Feeding will be of pinhead crickets, roughly 3 to 4 each, per week.
If they're anything like my E. flavicaudis they will be pretty straight forward to raise. I'm not sure exactly how long they take to mature but I'd guess somewhere in the region of 2 to 3 years.
