New Cave Biome: Coral Caves

I haven't really seen anyone suggest what I'm talking about, so here we go.

With the new cave generation, I think that there should be underwater caves. Like deep trenches (I know that's on the FPS page). But what I'm suggesting are shallow caves underneath coral biomes that have lots of drowned, glow squids, and a new mob: the electric eel. The electric eel would be a neutral mob that when you come to close, it will shock the water, dealing damage to the area around them, and will take 1-2 hearts no matter your armor, making them pretty dangerous. I don't know what they could drop, but please let me know your ideas.

I think that coral caves could be really fun to explore, and the electric eel could be really interesting. Feedback is appreciated!

Edit: Woah this did well
