So I've recently gotten started in bonsai and the other day I bought two young ones a golden gate and what was labeled as a Fukien tea but is a serissa kyoto which I've read up on and know is not for beginners. Now I've only had them for two days and it doesn't look like anything bad is happening but you never know. And I'm terrified that its going to die. Does anyone have any advice on what to do or what I should keep an eye out for?

Make sure you know exactly what species you have. Then take care of it as described on several sites. Do not fidget with it. Do not change too much at the same time.

Serissas like a constant environment, and hate sudden change.

They're not suitable for beginners, but if you water well and don't mess with it too much, it should be fine.

As JosephCooper has said, they hate being moved around. If you prune it, repot it, prune its roots, overfertilize it ou water it improperly, it could be sulking (no growth whatsoever) for weeks.
Put it outside, water it and leave it alone for the moment.
