Most "reef safe" crabs can and do catch fish if they're large enough. I had
a healthy flame angel in the claws of my emerald crab one morning. Most
people I talked to said it was probably already dead when the crab got hold of it. After doing some research, I think it was the crab. BTW, this
is the same crab I saw eat my entire colony of Zoas. I target feed my emerald now ;)
