crabs

Hi, are crabs safe if you have chorals in your tank? won't they harm the chorals?

It all depends on the crab. There are definetly some which are not reef safe, but there are others that are consider fine. For the most part hermits, emeralds, and sally light foots are reef safe. I do know that even those crabs can cause problems with corals. I would say that hermits are usually a safe bet, but anything is possibly when it comes to crabs.

*corals* most (not all) crabs that you find for sale on SW aquarium sites are reef safe and there is the occasional reported killer..
