Cornuboniscus is a small passive mob that spawns in the Carboniferous Dimensions Ocean.
Cornuboniscus swims around uncaringly until attacked by a predator or player. Cornuboniscus can be caught with a net, effectively taming them. They drop raw Cornuboniscus(60%) and small armour plating(20%).
Once caught, Cornuboniscus can be placed in an Aquarium.
