What to do with RLC

So I just got my hands on this RLC in giveaway chat and I don’t really know what to do with her now because I also didn’t really think I’d get her. Now the problem is she’s already quite old and I thought maybe it would be best to freeze her but neither do I have a Turritopsis Jellyfish nor the funds to buy one :D But I’m also not sure if I would be able to sell her since I am not that much of a pro and I really have no idea if someone would even buy her and if yes for what price I should try selling her. So yep any tips on what I should do?
