Arrow Crabs: totally reef-safe?

[flamehawkfish]

hi All

I have a 95g reef tank w' a mix of SPS, LPS, and softies- along with a few fish and a pair of cleaner shrimp.

I need a good critter to combat 'Flat Worms' in my tank. I treated w' 'Flatworm Exit' twice, but they keep returning! I even got a 4-line wrasse, but it's not getting the job done.

Somebody told me Arrow Crabs eat flatworms. Are they totally reef-safe? Will they do OK w' the cleaner shrimp? I have a bunch of SPS and Aussie Acans that I want to keep undisturbed, as well.

Thoughts? Please let me know.

Thanks,

Flame

Flame! you dont want any type of crab in a reef. JME, not even hermits.
a 6-line wrasse is what you need to eat any type of worm, flat, p-nut, bristle is higher on their chart, i think its the bite and spit till you dead and then ill eat you thang!!! :lol:

Arrow crabs will potentially go after a lot of different things when they're hungry. There have been a number of posts complaining about their predatory nature here on RC.

Melanurus wrasse ate mine. Arrow crab didn't touch 'em.
