So earlier today I noticed a hermit crab had fallen on a frag of lobophyllia that i have. I didn't think anything of it till later in the day when I saw something on the coral. As I was cursing every hermit crab in my tank for messing with my corals, I noticed that it looks like the hermit got the worse end of the deal this time around.
That's the end tip of his shell. It's all that's left right now. Poor guy got eaten.
