CUC for predator tank

[dreamcatcherr9]

For puffer and lion fish tank;
I know a CUC is also considered lite snacks for predators; but is there any CUC members might fair better than others (emerald crabs, conchs, Mexican snails, brittle stars)?

Or are CUC for predator tanks just something that gets restocked every few months?

You could try sea cucumbers.
