Cool/Interesting inverts for a nano-reef?

[NoahLikesFish]

I have a 10G cube that is a mixed reef, and I’m looking to get some suggestions/ideas for cool and/or interesting inverts. Right now I have a cleaner shrimp, a couple hermits, 3 trochus snail, and a growing army of baby nassarius snails.

The only thing that is off the list is sexy shrimp. I have had bad experiences with them in the past. I know they’re very cool, but I just don’t trust them lol.

Thanks!
