20 Gal. Tank. Lionfish? Eels?

[wadew]

I have a 20 gal. NUVO 20 reef tank with a oscellaris clownfish and a royal gramma. I was wondering if I could add something cool, like a lionfish, eel, or something like that (A dwarf one, kind of goes without saying).

I heard even dwarf lions will eat clownfish

Dwarf lions are too big for a 20g. Consider a red roosterwaspfish instead.

A melatremus would be about the only eel possible, but even then a 20g will be close.
