I am certain now there is a predator in my tank. I set up a bristle worm trap with a piece of raw shrimp in it last night, and now the shrimp is gone. So I didn't catch anything. It has to be either a flatworm or large bristleworm.
I'm going to continue to try my trapping efforts until this weekend, and if that does not work I will tear down my tank and dip everything in Bayer Advanced (read the threads elsewhere here about that).
Does anyone know for certain that will work, is it ok to dip live rock, and if I take everything out and dip it and put it back will that potentially crash the cycle? Aside from inverebrates and fish is there anything unsafe to dip?
Thanks for any input.
