why? I have one in my tank and hes just fine

I have also seen my emerald crab picking at SPS polyps... I gave him "the look" and he cut it out :lol:

I have 3 very small blue leg hermits living in my 2gallon frag tank. They have never once touched a coral besides by accedent tipping one over. One of them LOVES riding around on my banded trochus snail because that way he can clean the algae off the snails shell and get to the top of the tank. I also have many very small snails in the tank that the hermits just ignore since I have many already empty shells for them to move into.

Hermits are great for cleaning the sand in new tanks

interesting to see this thread getting more play again, so i will add another never again to the list..

bumblebee shrimp.... yes very small and cute but they eat the tubular feet of any and all starfish urchins etc...
