What fish eat starfish and urchins?

[Megalodon]

I know a porcupine puffer eats all inverts and that snowflake eels and lionfish usually don't touch starfish, but that's about it.

When I do my FO I would like some starfish and urchins if at all possible.

What fish should I avoid?

Stars and stripes puffers LOVE urchins for lunch(persoanl experience by stupid mistake)
