Reasons as to why Axolotls and Drowns fight

Axolotls and Drowns have a fairly poor relationship together and this is the result of multiple different reasons. One of the reasons is that they share a common environment and like how dolphins attack cod, and wolves attack foxes, they kill one another for the limited space and "Resources". (Also helps with lag). Sure... I am deeply analyzing a block game, but the Devs of Minecraft have put a lot of "Thought" into "Realism" in the game, so it is only expected that this conflict has a purpose. This leads to the second reason, which is to inconvenience the player. This is because unlike a tamed cat, a tamed Axolotl can do more than one thing. Where as a tamed cat will scare away creepers while constantly getting hurt and needing fish, axolotls give the player regeneration and attack mobs/as well as having outstanding abilities in water. What makes this even more OP than it already is, is that when attacked (If they don't die) they become "invisible" to ALL ENEMIES! Now back to the topic of why Axolotls and Drowns fight, one of the only creatures that can actually kill it are drowns with tridents. Thus it is reasonably that they would want to kill drowns given that they are one of the only enemies that can kill them (And are VERY good at it). Because of this it becomes a hassle for the player to keep there pets alive and so they can't be used to there full potential. Another reason could be because of some obscure facts. Like how axolotls in captivity often try to eat the plants that are used as decoration, could help explain why they attack drowns given that they have weird moss and plants on them. Now we get into some SCIENCE! When a Axolotl is injected with iodine, they reach their "Adult Form", and iodine can be found in plants. Plants like those on the Drowns, and a symptom for Iodine Poisoning is "Blue" skin. And because drowns become "blue" then that could mean they have a lot of iodine present in them. And so the axolotls might be "eating" drowns to try and reach there final form. Although there are many more reasons as to why they fight, these are some of the main ones.
