Axolotls can be found in Lush Cave biomes, spawning in underground water bodies under specific conditions: they must be within five blocks of a clay block, at or below Y:63, no more than five blocks above solid ground, and in complete darkness (light level 0). They typically spawn in groups of one to four, with common variants being yellow, pink, and cyan, while the blue variant has a rare spawn rate of 1 in 1200.
To tame an Axolotl, players must locate one, catch tropical fish in a bucket from a warm ocean biome, and feed the Axolotl with the fish. Axolotls will follow players underwater after being fed, but they require water to survive and can perish if out of it for more than five minutes.
Care tips for Axolotls include maintaining at least two blocks of deep water, avoiding excessive light, and noting that they do not eat unless bred. Axolotls can regenerate lost limbs if injured.
