Carnivores that stay small?

What about the Gumdrop Coral Croucher? Can you have more than one in a tank?

Ya, and are they aggresive, rare, expensive?

Yeah it wouldn't even make a habit of feeding salty fish freshwater feeders as treats. It's just bad food association. Shrimp are best.

They prefer to be solitary.

You could get several Kaudern's Cardinal, they're schooling fish that are commonly mistaken for freshwater angelfish. That will do well in a 30g tank provided proper "caves" and hiding places. They are also easy to breed.
