Lions paw medusa worm

[Woodstock]

Any one have any experience with one of these?http://www.liveaquaria.com/diversden/ItemDisplay.cfm?c=2733+4&ddid=115624
I think it's cool looking! or will it end up being a $35 scooby snack for some one like hermit crabs?

maybe the hermits will become food for it?

Care level says "easy," but I would probably have to disagree. I don't think most tanks would have anywhere close to the amount of surface area needed to just keep these cucumbers alive, let alone thrive. I've never heard of a synaptid, especially a large one, being alive in captivity for any real length of time, either.

It won't touch the hermits, but the hermits could potential damage the synaptid, though I wouldn't expect that to be the primary problem, unlike the above.

They get 4 feet though. Also, not sure how completely reliable this source is but

Fascinating and fun to watch, they are real cleaning machines for maintaining sand substrates, but are suggested to be kept in a non-aggressive species, non-fish aquarium, as genus Synapta or Euapta have been reported to kill fish if injured or stressed.

My guess is that even in the largest aquariums it will start to slowly starve right away since it gets large and is constantly being an eating machine at night. Since it's starving, it will start to go after live foods...

That caveat actually relates to the potential release of toxins when injured, etc. They won't eat fish or anything of the sort at all. They are surface mops, eating particulates from whatever fare they prefer.
