How do I put chalk ware/plaster fish on wall?
Answers:
OK, the answer may lie in what shape they are and how heavy they are.
If they are not too far out of round and not all that heavy, you may be able to use plate hangers to hang them up (link 1). They come in various size and strengths.
If they are not round or do not lend themselves to this for one reason or another, you can try going to your hardware store and checking the frame hanging section. I've seen peel-&-stick "loops" that you could attach to the back and then hang them. Or you could use velcro!! Just wander the "attach things to the wall" section and let your imagination run a bit. You'd be surprised what your mind can come up with!!
Good luck.

For any type ceramic I use plate hangers, There is less chance of them falling than with any other type hanger.
