New Arrow Crab Probmem

[FRANK GRAZIANO]

Just got a arrow crab on Friday and woke up this morning and it was eating my cardinal fish. The fish was not in the best health always stayed in the same spot since I got it 30 days ago. Don't know why other the it was a section of the tank with low flow . I'm worried the arrow crab might eat other fish it's only the size of a base ball and from what I read they usually don't eat fish till they get big. Anyone else experience this?

Remove it from the tank or you could possibly keep it well fed and it has a lower chance of eating your fish

Im having that problem with a large emerald crab. Ate a pearly jawfish, a lubbock wrasse and a six line wrasse before I figured it out
