It's kind of like asking "does your dog bite?" maybe not today, maybe not tomorrow, but one day he will. Crabs are jackals, they will take what they can when ever they can get it. I hate crabs lol

yes they will when roaming around they might bump them or fall on them from the overhang.

Crabs and other crawlies help remove detrius from coral that is not able to do so on their own just by walking over them.

2- Tromp all over your corals.
3- Knock frags over.
4- Kill each other.
5- Great for throwing into your sump.
6- Steal food from your LPS corals.
7- Just generally creeping out the wife.
8- Ensure your ailing corals will die.
9- Rip small softies from their rock.
10- Great toys for cats.

11. Eat the spines off of a large green brittle star
12. Moray and dwarf lionfish food

I haven't had any in my system for several years.
