re creature I found in the dark

[Nihoa]

we freshwater dipped our liverock and flushed a pistol out. we didnt soak for very long and managed not to kill our coralline or worse all the bacteria in the rock. ive read a less shocking treatment is to soak in less saline water for slightly longer. its more gentle on the rock and will still make it uncomfortable enough for whatever critter is in it to vacate.
