mantis shrimp - food?

[sindas]

would a bimac octo like matis shrimp? i figure it's usually a hated hitchiker and LFSs may just giv them out or sell them cheaply? just an idea.

Not a good idea -better to buy frozen shrimp for your octopus. A mantis shrimp can kill an octopus (and vice versa) but you don't want to take any chances.
If you want to feed live shimp, try the common shore shrimp.

sindas,
Roy Caldwell (Neogonodactylus) did a brief experiment (very brief) at Berkeley introducing a mantis and a blue ring. As I recall the expectation was that the octopus would consider the shrimp as food. The actual results were startling. The speed of the shrimp to spot, take down and kill the octo was almost too fast for the camera. I believe Roy still has this video posted on reef central and if this post is not enough to convince you to avoid an encounter, please research it further.

Mantis Shrimp are evil. LFS won't give them out, they sell them for about $20-$30 as people are willing to keep them because they are interesting.

I have seen video of this occurring in the wild. It would definitely not be the first food of choice but is a known natural prey item of octopods.

There is a possibility of injury to the octopus as with live crabs as well.

Be prepared.

The difference between a mantis shrimp and a crab is the Mantis will generally be smarter, stronger, and more aggressive. An octopus has a much greater chance of being successful eating a crab than a Mantis Shrimp.

PS - That video is really sad! I was thinking of a (pretty much) full size octo and a mantis that was at most half the size of the octo. My thoughts were reversed from what it really was though. I didn't see any ink from the blue-ring, which seems weird to me. Is it noticeable when they release TTX or is it only through a bite?

I don't think the octopus in that video had a chance to ink, or even see more than a flash of the Mantis before it was too late. It was most likely dead/severely damaged on first contact and the Mantis just kept pounding away to make sure.

There's video of one in the documentary film "Ocean Deep" defending its hole from an Octopus, appears to be a large Bimac. It was much smaller than the octopus, but it kept approaching the octopus, striking it, and running away until the octopus got the point and left it alone.

I've seen a large Mantis chop a damsel right in two, about as fast as this one hit that octopus. Ferocious creatures. I could have had one for free, but I didn't want to find out what would happen to my fingers if I made a mistake.

omg...wow


im so glad i asked this question on here. i'm gonnna have to make sure i don't get one of these from live rock and if i do get rid of it, i never even imagined one could take on an octo.

After seeing this video, mantis shrimp look way too aggressive.


And here's an actual octopus VS mantis shrimp:

That second link is the exact part of the documentary film I was referring to, maybe it's "Deep Sea"... all those film titles confuse me. Johnny Deep narrates.
