Thanks both for the reply's (and yes Elizabeth, I did understand the joke
)
I tried to reply 2 times before but the first time I pushed the wrong button, the second time I was not logged in 
Thirth time I type this now
There is a small kind of waterfall and, of course water, about 15 liter. I have put a pump in the water with no filter, just because I never see my capra in the water. This one I can clean in a few minutes.
As I have bought 6 small fish for my watergragons ones (5 died) and they never eat one, I know I don't want them anymore. Every week when I cleaned up the waterpart and filter, it took me half an hour to catch those little-fast-swimming-creatures.
Every morning and evening I mist the enclosure and for now the humidity is 77% in de daytime and 90% at night. I will see in about two weeks if this will stay the same. Otherwise I will buy a misting system to take over the hard job 
Under the tank there is a heatmat which warmes up the water a bit.
There will be some more foliage in there. First I wanted to observe her for a couple of days and I can see now she is doing well. I never saw her move as much as she's doing now. At nighttime she's moving to the highest and darkest place and hiding between the plants over there. (on the left at the top).
The plants are all fake but I will buy some real stuff for her.Probably better for fresh air and humidity.
Also I want to thank you for the reply of my older questions.
She's still 27 cm so it looks like she's just a small adult female.
But I have a new question.
Only ones or twice a week I find feaces (is this the right word?). It is huge for a small animal like her, specially the white part, that's about 3cm, 1.2 inch long. Sometimes her belly is also swollen up and it feels soft then. I didn't had de chance to bring some to the vet as I never knew for how many hours it is laying there.
When I just got her she was skinny so I fed her every day, as much as she wanted (5 or 6 crickets). Now she's a little spoiled because she only eat all kind of worms, she only eat crickets when she is very hungry. Now I feed her every other day, still as much as she likes, except when she is swollen up.
Any suggestions? (I will bring some faeces to the vet as soon as possible)
Doret.
