It’s ok as an occasional treat. Shouldn’t be the main staple but that’s imo.

Flint town!
As kno4te kno4te says not as the only diet. A good quality pellet should be the main diet.
Are the crabs freshwater or saltwater? Are they alive or dead? The reason I ask is that you could introduce a parasite or illness if it's freshwater and alive. If it's been frozen and it's freshwater or can be frozen any parasite should be dead or killed in the freezing. Salt water parasites don't usually transition to fresh water so they should be ok to feed occasionally.

In the wild rays eat crustaceans, so I think they would be fine with the crabs for sure.
