Sand Sifting Starfish and Crushed Coral -- 10/28/2009
Can a sand sifter star fish live in gravel?
Hi
<Hey Magenta! JustinN here!>
I'm am newish to marine tanks and I know this may sound like a stupid
question but thought I should do some asking before I do any thing.
<There are no stupid questions, we all start somewhere!>
I have a sand sifter in my tank with sand, but recently saw a tank with
what looked like gravel or some sort of crushed coral and really like
the look of it, so I was wondering if the sand sifter needs to live in
sand or
can he burry himself in the gravel/crushed coral?
Kind Regards,
Magenta Wade
<Assuming that we are talking about a crushed coral of Marine origin,
this should be no problem. Your typical aquarium gravel, on the other
hand, will more than likely be a problem. If you choose to go with a
crushed coral substrate, do be mindful of its ability to hold detritus
far better than fine-grain aragonite sand. It will usually require a bit
more cleaning to get all the mulm out of the crushed coral during water
changes, though the star will help in this regards. Hope this helps!

Snowflake eel; comp; now sand sifting star and cheap live rock –
03/03/08 Wow thanks for the quick response. <No problem,
Jiahua.> Yeah, I thought as much (but I don't think I have seen an
adult moray). It was only a spur of the moment thing when I go to my
LFS and see new things. And for your concerns referring to my system
and star, I got the sand and live rock first and let it sit there for
about three months (long enough?), before getting the moray and I have
around 2-3 inches of sand for my star. <If it is well populated (worm
burrows etc.), it should be okay. Personally I tend to wait almost a
year before getting sand sifting sea stars. Also I personally prefer
deeper sand beds (DSB) to help with denitrification. Compare:
www.wetwebmedia.com/deepsandbeds.htm .> Oh yeah, one more thing: No
matter where I look, live rock is always $6.99 a pound and I think it's
a lot of money especially that I'm only a senior in high school and
going to college. This was originally a huge project for school, but it
grew into more of a hobby. Do you have any suggestions as to where I can
find good deals for live rock? I want my snowflake to have more spaces
to hide than just one rock and some PVC. <I’ve had both, very good
and pretty bad experiences with live rock from fellow hobbyists selling
their stuff online. It is usually at least half the price, sometimes
cheaper. However, it is without a doubt preferable to see the rock and
select the best pieces. For high quality live rock the price you noted
above is reasonable in trade. Don’t put too much live rock into a
running system at once to avoid a mini cycle. Dead reef rock is much
cheaper than live rock and provides the same cover, but it won’t provide
as much biological filtration. I’d prefer live rock and add new pieces
whenever money allows.> -Thank you, Jiahua <Have fun. Marco.>
Sand sifting star and nano tank -11/17/2007 These are probably
really stupid questions and I fear this one may make your "funkiest
query of the day!" <Just hope Bob is too busy... ;-)><<As usual.
RMF>> Please refer to me the archives if I missed something in
searching. You guys/gals have answered lots of questions for us over the
last four months as we have upgraded our 90 to a 240. We are STILL in
process of doing the upgrade and I have yet another question. We have a
sand sifting star in the 90 with a DSB. <Ugh> We have only just
over an inch of sand in the 240 gallon and then a DSB in the fuge.
Despite their great reputation for starving and decimating the sandbed,
s/he has actually grown over the past year and seems to be ok.
<Unfortunately, many marine animals can take a very long time to starve
to death. If yours is growing, then I suppose it's not starving... yet.
However, I suspect your sand bed has suffered dearly. And once it can no
longer maintain the star fish (an inevitability), it will slowly die.>
Does the star stand a chance in the 240 without a DSB assuming the tank
has several months to establish fauna in the sandbed before the star
makes the switch from the 90? <Sure, it would probably live longer.
But again, you're just delaying the inevitable. And what of your poor
sand bed?!"> Okay, on to the stupid part...my husband is the reefer
and I merely stare at the pretty fish and read your FAQs, but I am
trying to do an informed Christmas present. (Hope he isn't reading the
FAQs today!) I want to get him a nano tank for a shrimp/goby combo. Due
to the instability in this volume, I was hoping he could just plumb it
in line with his main tank <good idea> since he already has lines
going everywhere under the floor because the sump and fuge are in a
different room from the main tank. Plus, he loves such DIY projects. Is
this reasonable? <I don't see why not. In fact, I frequently
recommend this to people who want to keep a nano tank and already have a
more "regular sized" system.> If so, would one of the 24 gallon Nano
Cubes be an option, or is it impossible to modify their set up? <I've
never had a nano-cube, but from what I hear, I don't think they're so
easy to set up this way (because of the hood mostly I think). How would
you get the plumbing in/under the hood?> Surely you can at least add
a sump and/or fuge to the setup??? <Of course you can.> Is there
a different brand you would recommend over the Nano Cube? <Again,
I'm sorry I've never personally had one of these. But if it were me, I'd
simply go buy a small glass tank and proceed as if it were just another
remote sump or refugium (as you put it). However, I'd do a little more
of your own research on the Cube. It might work just as well, I honestly
couldn't tell you for sure. I'd only wonder about how you'd get around
the top of it.> Thanks for any information and I apologize if I
missed answers in the archives. Your time is always appreciated!
Michele <De nada, Sara M.> Sand Sifting Starfish
Hi Bob Please could you help me, as I feel that I may have been
wrongly advised I have a 50gal tank which has been set up for five
weeks, (set up with RO water ... been testing... all is well) I recently
went to buy something to help with a coating of brown algae on my 3inch
sand bed, I was sold a Neon goby and a sand sifting starfish I looked on
your website to read all relevant info on sand sifting stars, now I'm
worried that my tank is to small and to new to keep it well fed I also
have 2 turbo snails, 1 bumble bee snail, 1 shrimp and some live rock,
(no fish yet) I run a Prizm skimmer and external Fluval 404
I have had the starfish for a few days .... so far all is well,
Please advise Many thanks Sam >>>Greetings Sam, Your
tank is indeed MUCH too small to keep a star such as this alive long
term. Besides, it doesn't eat detritus, it eats the sand bed fauna that
we work so hard to establish. Back to the point, it will slowly starve
to death after it has depleted your sand bed of food. You need at least
12 square feet of sand bed to sustain one of these stars. Again, you
don't really want one in your sand bed anyway. You need to look to
nutrient export to get a handle on your algae issue. Cheers

Sand-Sifting Starfish (Needs Lots of Space!) - 07/16/05 I was
thinking about purchasing a Sand-Sifting Starfish, and I was wondering
if it would harm other star fish? I have a brittle starfish and
a chocolate chip star fish. I also was concerned if it would harm a
scooter blenny? <<As a rule no, it won't harm the organisms you
mention, but do research/rethink this purchase (start by having a read
here:
http://www.wetwebmedia.com/sndsftstrfaqs.htm). These creatures
can/will deplete the biota in a sand bed very quickly. This in itself
is not good for your tank, but bodes even worse for the
starfish. Unless your tank is large (125g or more) with a mature DSB,
this animal will likely starve to death within a year. Regards, Eric
R.>>
Astropecten polycanthus...Not For A 29 Gallon
Tank - 11/10/05 I recently purchased a Sand Sifting Star. I
notice the second day that it had lost two of its arms. I have a 29
gallon tank with one Coral Beauty Angel, live rock and sand. The water
tests fine with the nitrate a little high <<how high is "a little?">>
with everything else in the normal good range.... Do you think the angel
got it or is the nitrate level? <<Could be the nitrates...doubt it is
the angel. More likely, the starfish was already sick/injured when it
was purchased.>> Thanks for you advice Sandy <<Please do be
aware, injured or not, Astropecten polycanthus will not survive in your
tank...it is much too small. These animals need much more substrate
than your tank can provide in order to find enough food, and even then,
will quickly decimate the biota in the sand bed. Regards, EricR>>
White Sifting Star question Have a 55gal tank with a 10gal
(refugium/sump) established for about 1 ½ years with 50lb of live rock
and 40lb of live sand with a snowflake eel, a harlequin tusk,
<This fish needs more room> a cardinal, 1 ocellaris and 1 blue
damsel fish. Also some coral/inverts like a crocea clam, frogspawn,
green Goniopora, yellow polyps , some xenias, red mushrooms and a
speckled leather coral, a couple of hermits and snails for clean up and
2 white sand sifting stars. I think because of the refugium, which has
Caulerpa and 4 mangroves plants a good supply of what I think are
amphipods have developed (I even discard some when changing the filter
pads). The reason for this post is that after reading some pages of the
Marine Invertebrates book in which mention that 1 sand star will require
6 square feet to sustain it I wonder If my 2 stars are slowly dying.
<Mmm, evidently not... some systems (like yours apparently) have much
more food...> To me they look ok, they move around, burying and
emerging form the live sand and even one of them re-grew one of its arms
after the harlequin attacked it. I have had them for around 10 to 14
months. What do you recommend, taking out one of them and maybe put it
in the fuge or give it to a fellow aquarist or keep both of them. <I
would get a larger system period... if you can afford and fit it in...
Bob Fenner> Re: White Sifting Star question Thanks! I'm in
the process of getting a larger one(125gals). <Ah, good> Just to
clarify, the book I'm reading is not Marine Invertebrates, is one of
your books Reef Invertebrates. <Yes> So far it's great, I'm now
in the refugiums chapter of the book, lots of new information to me and
been honest, I can't stop reading it! <Outstanding. Thank you for
the report. Anthony and I really wanted to "expound" on the virtues of
such technology... urge people to investigate, use refugiums... and
really "used the excuse" to cover principal marine invertebrate groups
as a springboard if you will... to proffer the hundred or so "other
pages". Cheers, Bob Fenner>
