Unique Ideas for 20 long (fw or sw)

[Dcal]

I picked up another 20 long to add to the collection and want to do something unique. It can be fresh or salt what would you guys do with it.

Current Ideas:

salt:
Mantis shrimp
Temperate macro and inverts
Aptasia tank?


fresh:
fiddler crabs
frogs
pea puffers

or brackish and get a puffer

I've heard of some people getting a bunch of really ripe live rock giving it light and reef roids and just seeing what develops (sponges, gorilla crabs, worms, feathers, etc.). Sounded like a kind of cool "mystery box" type of tank to me. Others have called it a dedicated "pest" tank, lol.

Lionfish, waspfish, and I believe the coral croucher are all venomous

I like the idea of an aptasia tank or a tank you dont care what you add too. Like you can get whatever as long as size restrictions apply. Lol.
Id just do inverts.

This would be my favorite little venomous fish for a 20g, pics don't do them justice and they have a cool personality. Fun to feed live, but will take dead.
