Axolotls and glow squids spawn in ocean

Hi i host a minecraft server for me and my friends and we found this problem. The axolotls spawn in the open ocean. This is annoying and strange to us. it messes up a lot of things. i was lead to believe that axolotls only spawn in the underground caves, but they are spawning in the open ocean as well. They mess up drowned farms, as they spawn and kill the downed before they can reach the farm. and also they kill all the fish and squids and glow squids (which i thought also only spawned in the caves btw) and they ruin the ocean's nice aesthetic feel a bit. (and leaves junk floating all over the ocean) I feel like they need to be special only for the caves and be something that you can get from there, and also this means they can spawn near ocean temples, destroying the point of having to go find them and scoop them up in their cute buckets to bring along with you. they also make it so getting tridents is very hard because they kill all drowned before you can get to them with your looting sword. if you could look into this that would be great and i realize that I'm pretty sure they will only spawn in the lush caves in the future when the world gen part of it comes out, but this still means that any part of the ocean that has lush caves will spawn them there, and also that this problem will effect the summer update too. thanks for reading this and i hope this problem is looked into cause its very annoying
