I used to have a coral banded shrimp which used to have a fire fish that slept next to him every night. It seemed as if the coral banded was guarding the firefish. Was this normal behavior? Because I have read they are terrible creatures who will eat small fish like firefish. Eventually the coral banded died and the firefish died shortly afterwards. I am wondering if this is normal and I can get another coral banded without it killing my gobies or will he eat my fish?
