Zygopetalum with shriveled pseudovbulbs care

[Iray]

Hello!
I bought a new beauty on sale, it's a zygopetalum. It has shriveled pseudobulbs and leavesnare not very 'straight'.
Now, I have no idea what to do do with it! There's some bulbs that don't have leaves as well. Is it normal?
I repotteded it in fine bark and expanded clay mix and the roots seemed really good with new tips coming out! Yet!
I've noticed theres green tips coming out, are they spikes?
If you could direct me on how to take care f ten and prevent disaster I would be so grateful!! Thank you!
