What To Do With 20gal?

[Inchyally]

I am very soon going to start moving my fish slowly into my new 55gallon. Probably next week. I was wondering, what should I do with my 20 gallon? Here are my ideas, if you have any more, suggest them.

Hospital tank
Breeding Tank
Female Betta rescue tank
Let my dad have the tank
Or put it in storage.

Set it up!!!!

Get creative with scaping it and have another tabk, or depending on how many fish you already have and how often you require a hospital/ qt tabk use it for that.
