YEah , I TOO hate Ampipods.. little bastards demolished several colonies of prized zoos... not anymore, I've since turned my tank to a wrasse tank... filled with ( Blue sided, mystery, esquisite, carpenter, red and another I cant remember wrasses ).. they constantly patrol my tank and basically devour anything.. be it a pod, tiny crustecean, nudi or what ever .... best thing I've done for my tank.....
I also had a pipe fish patrolling my 20QT till he got sucked up in my PH when I was cleaning the foam guard.
