Rock Nem Experience ?

[Z06-Hec]

Anyone good with Rock nems?
My buddy has had one for about 2 weeks and it moved a bit and finally attached to the glass....
from the glass it walked all the way up to the top of the tank. It started to make its way down and made it about half way and then today walked back up to the top....
It also left some slime on where it walked up to the top.

Generally too much light or flow I have found makes them move. Place it in a nice shaded corner away from flow. She might move a few inches but should settle in nicely.

Each nem is different though, some will stay put for a while and some will move around quite a bit until they find a suitable spot.

I thought the same but if she is getting too much light why would she move higher instead of lower?
The flow is very easy, as i had him adjust it. I judge by how the goni on the sand flows... its just swaying lightly as before it was blowing all over the place.
