Subaquatic

Ocean biomes, sea creatures and underwater blocks make up most of the additions. Fish, cod, salmon, pufferfish and tropical fish entities join the world, and kelp, seagrass, sea pickles and coral generate in oceans. Glow lichen, mud and mud bricks, and hanging roots generate under properly coded trees.

Other changes cover chest boats, ender chest boats, crafting table boats and furnace boats, bubble columns working on water, and a new villager type, the marine biologist, whose trades are the only source of froglights. Fishing reels catch real fish entities instead of fish items, and an enchantment counters that effect. Smooth stone, sandstone and quartz variants are added, along with lapis lazuli blocks.

Subaquatic depends on AssetMover and Fluidlogged API, both of which must be installed alongside it. The mod runs on the client and the server, so both sides need it, and it is published for 1.12.2 only. Its code is all rights reserved and is not open source, although the source code and issue tracker are publicly linked. Other mods can use its serves library to add their own custom ocean biomes.
