Underwater Lakes

As part of a future cave update, I purpose adding more underwater lakes, however, these lakes would be sizable, and generate with unique bioluminescent vegetation growing in them, and connect to other sections of the cave. This would encourage more uses for respiration and water exploration, as players could dive beneath these lakes in search for other secrets the cave could offer (as part of a cave update). I also recommending adding 3 variants of bioluminescent fish as passive mobs, and a non bioluminescent but dark colored eel mob that eats them, and would attack players swimming in their territory.
