Longnose decorator crab

[reefer134]

Hey I just wanted to see if longnose decorator crabs would kill fish and inverts?

Never heard of them killing fish however they will mess with your corals. I had a decorator crab in a store once that tore apart a leather coral however they just kept growing when he put them on, that obviously won't be the case with most corals, but they also put dead fish on, I had a six line with a swim bladder infection die and the decorator crab was carrying him around on his back
