AxolotlSterilizer — серверний Fabric-мод для Minecraft 1.21.11, який дозволяє “стерилізувати” аксолотлів і назавжди забороняє їм розмноження.

Функціонал

Команда /sterilize робить аксолотля стерильним
Стерильні аксолотлі не можуть розмножуватись
Взаємодія з тропічною рибою для розмноження блокується для стерильних аксолотлів
Стан стерильності зберігається на сутності та не губиться під час відро → підібрати → випустити назад

Frequently Asked Questions

Axolotl Sterilizer server crashes on startup – what to do?

Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.21.11). You can switch loaders with one click in the panel.

Is Axolotl Sterilizer compatible with fabric?

Axolotl Sterilizer officially supports fabric for Minecraft 1.21.11. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with Axolotl Sterilizer – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Axolotl Sterilizer consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
