    Hi guys, i'm looking for ideas for a fish/invert that will stir up my sand. Hopefully something that does not eat pods, or is a ferocious pod hunter cause i'm trying to increase my pod population at the moment. The reason is i've now sorted out my flow in the tank just the way i want it. Detritus in suspension goes over the overflow, a the wavebox picks up detritus from the top of the sand bed. But nothing picks up whats in the sand itself, unless a fish swims past in a hurry and stirs it up.

    So what will unearth the detritus from INSIDE the sand continuously so i do not have to rake it myself? I've heard of a burrowing star-fish? I'm not so sure of sand sifting gobies cause of their pod eating needs.. so ideas? Prefferably from your own experience?

    Hermit crabs mate. You are in the "land and honey" when it comes to marine life-stock. Go to the rock pools and collect your quota of hermit crabs. They work great. Otherwise - yes. A burrowing starfish (the "sand-sifter starfish").....

    You need one of these fellows - sand sifting starfish - Astropecten polycanthus

    Awesome little critters, spend their lives under the top layer of sand and occasionally come up for air and a walkabout.

    i've got hermit crabs, all a little bigger than a one rand coin, none burrow, they do clean up any food they find on the surface which is not much if the fish are smart. I'm talking deeper in the sand, cause over time quite a lot of detritus settles in the sand, trying to think of the stuff here that seeps into the sand. My sand is about 3 or so cms thick in most places, some deeper, some shallower, would that be ok for a sand sifter or would it not be deep enough?

    Shut up. :p Dove snail - nassarius vibex, these critters are awesome detritus feeders, they breed like mad and also live under the sand with their little snouts sticking up, when you feed the tank they sense the food and your sand almost bubbles with hundreds of these things coming up to the surface to feed.

    golden head goby.

    But they can drop substrate all over the lower rocks. The coarser the substrate, the higher they swim before they sift the sand. Playsand and descend flow, they keep low.
    Just be sure they can not dug under and tumble rocks.

    Else a lot of the other gobies are excellent.

    They will do exactly what you want to achieve.

    I keep the Super Tongan Nassarius snails. The Nassarius vibex are smaller. Both will sift through the sand. The Super Tongan Nassarius are difficult to breed in captivity.

    I have a golden head goby and three of the local blennies - they make a mess putting sand everywhere I don't want it, but my sand is definitely stirred...
