The tank began as a pet project. On 15 July 2021, prop had “made a tank for my axoltl” 1. He soon noticed that the dark water below Y63 behind tinted glass was where axolotls and glow squids spawned naturally 2, and the tank filled up: five axolotls, then seven, including a white one 3.
By 19 July it had become a deliberate spawn box, one that mimicked axolotl spawning conditions, fully dark and below sea level. Prop presented it as “axolotltank” 4, while correcting himself on who had built it: kira 5. Kira marvelled on 20 July at “so many axolotls sheeeeeeeeeesh” 6. Prop and kira bucketed some up into an “axolotl army” 7 to try on an ocean monument. See Axolotl army and Axolotl Mania.
