I keep a 1cm Chilobrachys fimbriatus spiderling in a 10cm high, 7cm wide glass jar which is 3/4 full with substrate and has vent holes in the lid. I've had it for about 3 weeks and I've only seen it once. It spends all of its time in a burrow which I made for it by poking a pen into the substrate. I know this is normal for this species, but I am dissapointed because from what I've heard they can make intricate networks of tunnels and are supposed to be heavy webbers. So far the spiderling has neither expanded on the burrow which I started, nor made much webbing other than a bit of very thin webbing just around the burrow entrance. Poor effort! Any suggestions? Cheers
