Arrgghh!\nI had what seemed a perfectly healthy cardinal just die mysteriously. We found him covered with feasting hermits. The emerald crab has been nipping at my other fish and the bigger emeralds have been known to kill fish. My fighting conch disappeared a few weeks ago and then I finally see him crawling from under the rocks but now there are these little blue legs coming out of the shell. Of course my mandarin goby, (everyone predicted his doom), eats prepared foods twice daily and has not made a dent in my pods.
