I just dropped some NLS pellets in my tank for my fish and one of them happened to fall on one of my lavender mushroom polyps...Well one of my huge gray hermit crabs went into a feeding frenzy and went over to it and started pinching the polyp trying to get the food...He did not actually tear the polyp whatsoever, but it shriveled up and puked a bunch of white stringy stuff from the center. Is this particular polyp toast? It looks like it's opening back up...I'm currently looking for somewhere to get rid of these crabs as I hate them. They knock everything over in my tank, crawl on my corals causing them to close, fight with each other, etc....I can't bring myself to execute them and I don't have a sump so I'll see if I can pawn them off on one of my LFS.....
