Inverts for a mostly Fish Only Tank

[Clowning_Around72]

So, I just redid my 60 gallon tank and replaced a tomato clown with a pair of ocellaris clowns.
So, the current stocking is:
2 ocellaris clownfish

There are no inverts in the tank since it was being kept as a FOWLR setup.

I don't have any major preferences for inverts aside from I'd like to keep the clownfish and I don't really care for trying corals in this tank.

I may add 1-2 more fish but I am quite certain I would like to use this tank to focus on some inverts that I normally would not be able to keep with coral.

Any suggestions?

I'm just looking for some ideas. Preferably, inverts that I otherwise wouldn't be able to keep in a reef.

Options may include giant hermit crabs, decorator crabs, and peacock mantis shrimp. Good luck with whatever you choose!

I would also like more than 1 invert and for them to be compatible with the 2 clowns. I'm not sure if I will add more fish given this tank has usually been kept lightly stocked over the years, but a few nicer inverts would work for me.

Maybe some sort of shrimp or starfish species?
