MoreFish

Most of the added creatures can be tamed, and each tamed method gives the animal a function such as helping in combat, healing the player or granting buffs. Tamed companions follow the player through a following system, so they stay close rather than wandering off. The author notes that more new mobs are planned for future updates.

The mod targets survival and adventure play in the ocean biome. Divers can meet predators such as Great Whites and roaming Orcas, while the tamed creatures serve as allies. Players install MoreFish on the client and on the server, since the environment is client and server and both sides need the mod. It is released under the MIT License and is not open source.
