Tips on adding a new ACF to my tank?

[CaitlinAnn]

Hey guys. First of all, I am really excited to let you all know that I will be adopting a full grown female ACF tomorrow. She will be sharing a 20 gallon tall with my male albino ACF. I was just curious if there are any tips or advice you all could give me?

I thought it was best practice to quarantine her for a bit in a 10 gallon just to ensure she's healthy, but is there anything else I should do? I am really happy to have her and I've been considering adding an adult ACF for awhile, and this opportunity just presented itself. Size shouldn't be a problem. They are both adults and he is about 3.5-4 inches stretched out. Also the previous problems I experienced in my tank are cleared up, so it shouldn't be harmful to add her.

As for my 20 gallon, its equipped with a whisper 20i, just did a water change yesterday, chems are fine. No heater. Its planted with a secure cover and some hiding places. Is there anything else I should do? I would love to add her immediately, but I'm assuming that wouldn't necessarily be best for Ghost or the added female. There is no problem with quarantining, I will be getting a 10 gallon tomorrow, and I am fully prepared to do whatever is necessary. I'm going to continue doing my own research, but I really wanted your advice. I've only ever kept Ghost by himself, so I don't know exactly what it will be like to have two. I know they're primarily docile creatures, and aren't necessarily prone to territoriality issues, I don't want to put Ghost or the new girl in a situation where either could be harmed.

Anyways, here is my set up. I'm sorry if I sound rambly, but I'm incredibly excited to have her. She needed a new home and I'm very happy to give it to her.
