Really?
 

All the "bad" crabs I have seen are fast as lightning. I had two in my 20 at one point and good luck trying to get them. Even look the wrong way and flash! GONE!

I would like to see him try. No really, I would love to see that action! :twised:

Uhhmm, underground crab fights...... maybe I will keep him :lol:

This is why I hate crabs! They turn into monsters. I had one in my reef, (a little smaller than yours), that killed hundreds of dollars worth of corals before I finally was able to spear it with a metal turkey skewer. Then the hermits in my frag tank took out a bunch of zoas. Corals are hard enough to raise without some 8-legged, stalk-eyed monster snacking on them. KILL THEM!!!
