New to zygopetalum help needed

[Hellya1]

Hey! I am totally new to zygopetalum and can’t find out much about their care on the internet. Mine seems to have finished flowering but what do I do now? Do I wait for the spike to turn brown like I do for my phals or should I cut it straight away? Also there is now another growth (see photo) at the bottom of the plant would this be another flower stem or a new pseudobulb? I really have so much to learn about these lovely plants 😀
