Thanks for the nice comments everyone!
Hey i really want to know are knob tails or spiny tails hard to keep ?? like care and how big do enclosures have to be and Lars i would love to see those AWESOME geckos enclosures =D
No, these two species aren't so hard to keep.
Here's a care sheet for the N. wheeleri:
Nephrurus amyae - N. wheeleri
The Strophurus williamsi needs a tank size of around 40 x 40 x 60 cm for an adult
pair. The temperature should be up to 35°C under a basking spot and it should
be a temperature gradient in the tank with lower temperatures of around 20°C
near the ground and up to 28°C at the top during the day.
At night the temperature can drop down to around 20°C.
Some UV is beneficial for them.
The humidity should be around 50 - 60 % during the day. You can mist
the tank from time to time, but not too much.
As a substrate you can use pine bark, coco fibre or a mix of coco fibre and sand etc.
Diet: all sorts of small insects like crickets, small roaches etc., dust the food with
a good calcium/vitamin powder.
Setup: a lot of branches (thicker and thinner ones), plants and a small flat water dish.
And here are pics of the enclosures:
