Introduction
This mod aims to add many different kinds of fish and underwater decorations to the game. This mod is meant to be as simple as possible while still adding good quality things, new items, new fish, new blocks, new plants, and more. This mod does NOT add any new biomes, NO new dimensions, all this mod adds are additions to the already existing Minecraft oceanic biomes.
A lot of the mobs added by this mod can be caught in a water bucket.
This mod is for Forge and there will never be a Fabric port.
