Interesting concepts for a 25 gallon tank?

[Hexabonal]

A friend gave me a 25 gallon all in one and I'm not sure what to do with it besides my main tank. I thought of just filling it with weed corals and putting in some nasty anti-social fish, or filling it with mangroves and having coral grow around the mangroves. I would kill for an anemone tank but they need to be old and stable, right? What would you do? Any species you would use?

Go as cheesey as possible, let your other tank be the nice refined tank. I’m talking fake sunken ships, fake clams that burp air bubbles, no fishing sign, maybe a little scuba diver guy, etc. Then, fill it with nice macro algae, soft corals, and a whatever small fish fit your fancy.

Frag tank or QT. I’d dip corals and place them in that tank.

With an AIO... I’d be tempted making it a second display tank

Plumb it into your main and use it as a nem tank
