Axolotl ideas?

So the axolotl is finally in the snapshots now and I absolutely love them there so cute and outstanding. So i have a few ideas the axolotl can be tamed with tropical fish (finally give them a good use) and they will attack elder guardians regardless (i saw they didnt do anything when holding tropical fish) and that they should at least defend themselves when under attack by a hostile mob (they dont do anything) so please if its a random bug or just in the code so just patch that up (and also the regeneration effect to the player isn’t working either).
