Arrow crab is bored

[tent boy]

Almost a year ago, I bought an arrow crab for my sump. I saw a couple of small bristleworms in there. I hate those things. I purchased the "exterminator" to take care of the problem. I have been feeding him every other day since the worms are gone. Can I assume that he could not survive in a tank with fish and coral bandits and the likes? Does he need to go to a nice nano tank?

they fish may not survive! I had an arrow crab grow so big that he would REACH OUT OF THE TANK when he was hungry! He was so scary. he looked like an alien. If he was even a few inches bigger there would be horror movies written about him. Sequels too!
