Pin of fish command

From Ardrana

The pin of fish command trident-shaped piece of jewelry is studded with pearls, sapphires, and coral. The item must be attached to an item of clothing or worn around the neck as a pendant. Also, its command word (engraved on the silver back of the pin) must be spoken to activate its enchantment.

Its magical properties enable its wearer to empathically command fish within a 60-foot radius. The wearer of the device can cause fish to move in whatever direction is desired and can convey messages of emotion. It does not affect mollusks, crustaceans, amphibians, reptiles, mammals, and similar sorts of nonpiscine marine creatures.
