Best invert for sandbed cleanup

so my tank is getting better, its about 5 weeks old, livestock is listed in my sig. but my question is will anything eat the poop(for lack of better term) that my two electric blue hermits have been leaving, they are awesome at cleaning the rockwork and a cool addition, but they crap everywhere, also it seems like a lot of dirt settles on my rocks, is there something to keep that clean as well, other then thatg the tank is doing great perameters are very good, coral is looking good, all inhabitants working hard and very mobile

 

Sea cucumber! which actually looks like a turd itself. I just picked up a large pink one yesterday from LFS. Its anus amazes me.....

 

LOL...cant they release toxins though, if the die or get stressed? its a small tank to so it have to stay kinda small, only a 12gal

 

Only if they fear for their life, like getting picked on from a predator. If you have a peaceful tank then they are a great addition. I have a tiger tail cuke and love him.

 

Sea cucumber and also most reef safe stars eat poo,oh and copods

 

My lfs has some horseshoe crabs, they said they are decent sand filter feeders. Thoughts/Experiences?

 

I got a horse shoe crab and it died a week later, didnt seem to eat and i never saw it, was always buried in the sand - a sand shifting starfish might be better, altho you would have to check if they are reef safe

 

Not good reef inverts as they are clumbsy like most urchins. They grow large and may knock things over.
I love the Sea Cucumbers and the Conch!!!!!

 

Sand Sifting Sea Stars are not a good addition in my opinion. They are not very hardy, require alot of space with which to forage for food and their track record of success isn't that good as they seem to die in a short period of time, probably due to starvation in small aquariums!

 

I am actually thinking about getting another cucumber for my tank as I don't think one can keep up.
