Yeah, I see this often with new arivals.. I wouldnt worry. If after
a week and its still on the glass I would check some water perameters

Thanks for the info. I got it from your store Saturday...
Did you get these guys recently? It was on the glass in your tank as well.

And what water parameters would be important for these guys
to stay burrowed in the sand bed? I put it in the tank where
there is almost no animals - almost macroalgae-only tank,
with lots of snails, one crab and lots of sand bed creatures...
So there is no nitrates and calcium level is pretty high.

p.s. we could not find any mini-stars in the tanks this day
I got one pound (a cup) of live sand instead but after I inspected
it home in a very flat dish and a 10x magnifier glass there was not
much life in it: 2 tiny worms, 2 tiny snails and no stars unfortunatelly :-(
