Pretty interesting creature, just be weary. Some arrow crabs have a tendency to hunt other inverts in your tank. I just got my arrow crab a few weeks ago and I've seen him eating 2 of my blue legged hermits. They will eat anything they can get their pincers on. Still worth it just so long as he doesn't eat everything else in your tank

Fun to watch and great algae eater!

I've just started my first full marine tank. Have had a little experience with fish-only before. I got an arrow crab, along with a crab/snail kit from saltwaterfish.com (about 50 of the little critters). Two weeks later, there's a small graveyard of the smaller ones in a pile behind a piece of live rock. I think it has to be the arrow - but it's totally worth it. He's creepy, pre-historic, and puts everything in his mouth (then spits out what isn't food). He hides about half the time, and takes harmless swats at fish as they get too close. Add one to your tank.
