Hello,

I have quite a few aquariums set up in my Windows 10 Bedrock Edition survival world. Axolotls are cool and always will be, but I was beyond enraged at this. It took me a lot of time and hard work trapping a guardian, getting it into my boat, and into my island's prismarine aquarium... the guardian was named and everything. The same thing happened with my named squid and named glowsquid (at first i thought they were despawning then I saw this). Now I'm scared to have any aquarium at all, if an axolotl spawns inside, it will kill whatever else is in there with it. The official Minecraft Wiki (https://minecraft.fandom.com/wiki/Axolotl#Spawning) states: 

"Adult axolotls spawn naturally in groups of 1-4 on any water with blocks above it below y: 63, typically in caves. This includes bubble columns.

After the world generation, axolotls spawn individually in total darkness and where there is a block with base_stone_overworld tag (i.e. stone, deepslate, andesite, diorite, granite or tuff) less than 5 blocks below the spawning space."

Every aquarium in my world is well-lit and doesn't have any exposed natural stone inside! It takes hard work and is time consuming capturing the ocean mobs and getting nametags. I'm reluctant to try capturing more fish, guardians and squids and naming them with nametags knowing an axolotl can spawn inside the tank and kill them all over again. It's really hurting the progress of my summer build project in my survival world. Please fix this ASAP Mojang!!! I know a lot of players who love building aquariums. Imagine having an aquarium full of beautiful ocean mobs for years in your survival world just for some wild axolotl to spawn in and kill them all.

Thanks.
