Dendrobium helix seedling care

[Iray]

Hello!
I just received this den helix seedling.
It looks good I think, just a bit dehydrated and two leaves damaged from transport...
It was 'wrapped in coco husk slabs kind of thing, so I left it there, soaked it in water, and put it in a small pot and added some sphag around the roots and on the sides to keep the moisture better.
Am I doing this correctly? Is there anything I should do?
I've tried to look on the internet but there's not much info out there

OK, update! The seller told me to remove the moss as it will kill the roots! So I put some expanded clay around instead to stabilize it in the pot so it won't move around. Good idea??

No more moss
