Crabs are opportunistic predators and I wouldn't put any money on the new addition restricting its diet to only things that you want it to eat. It's always hard to predict what an individual emerald crab will or will not eat though: it seems to vary a lot by individual. On the plus side - it should be easy to catch if you need to take it out of your sump right?
