Just want to say that axolotls can spawn, but due to lack of water and the spawning conditions set to prevent them spawning in 1.17.1 the only place they spawn is in aquifers that rarely border lush caves. This problem was also applied to the experimental generation as well. However, the problem is with the spawn conditions as axolotls are really only obtainable by making an axolotl spawner.
