Minecraft Dungeons:Tropical Fish (mob)

A tropical fish is a passive mob that first appeared within the Minecraft Dungeons Cross-Platform Play Trailer where three of them are seen swimming in Dani's tank in her home, and were planned to appear in the Hidden Depths DLC.

Behavior
They are mostly seen swimming across missions in shoals, and they scatter away if a hero catches up to a shoal and attempts to attack it.
