I can't stand these damn Nass. snails anymore!!! Everytime I go to feed my Duncan or Acan they come storming up from the depths of hell to steal said food directly from the mouths of my coral. Is it wrong that I didn't save one that had rolled over from the clutches of a scarlet hermit??? I don't believe so. I look at it as the snail had his last meal. I'm gonna get a piece of PVC from work tom. to surround my duncan. Or would they take advantage of that?
