NoCoralDeath

Keep your coral blocks and fans alive with this simple Minecraft plugin! Compatible with versions 1.17 to 1.19.X, it utilizes the randomTickSpeed gamerule to prevent coral from fading or dying. Never worry about losing your beautiful underwater decor again!

No, but for real: This plugin checks if the randomTickSpeed gamerule is set to 0 in the world. If it is, the plugin will prevent coral blocks and fans from fading.
