What kind of relationship do you plan to have with Nalani?

What I'd like to know is why Nalani doesn't appear in the Manage Households menu? She's not even in the Not In World category. Is she hidden?

Since she's a mermaid, she'll only show up if you're playing as a mermaid. Same thing with normal sims. If you only play with those, mermaids will be scarce. The devs did that on purpose, I guess to not break immersion if you just want regular sims.
