Need help selecting clean up crew for "new" tank

[Warthur]

Hey guys,
I have redone my 30 cube and am going to begin stocking it with it's first fish next week. However, I need some help in selecting the cleanup crew for it. The first fish I am adding is a golden dwarf moray. While they are reef safe, they are definitely not small invert safe. Any suggestions on alternatives such as stars or cucumbers?

Conchs are too much for gdm to handle, so are tuxedo urchins.

I like Astera and Trochus Snails, I'm not a fan of any crabs
