What plants will my crabs NOT eat!?

[aquasteph]

I don't mind feeding my crabs some anacharis, which i know they love and eat, but are there some plants that my red-claw's WON'T eat? I'd love to have some natural decoration other than rocks in their tank but they eat up everything I put in there.

Any suggestions? :help:

I'd try java fern and/or anubias, if they eat those then your only recourse would be plastic or silk plants.
