Did you get these guys recently? It was on the glass in your tank as well.


yes, just last week.. Most of ours are now down in the sand bed

And what water parameters would be important for these guys
to stay burrowed in the sand bed?

They dont "burrow" in the sand.. they scoot along the top, mopping sand as they
go..

A/N/N would be the only things that I would be concerned with when if cukes
climb th e walls and never drop back to the sand.
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 :-(


This really supprises me.. just yesterday I piced up a cuke off of the sand for
a customer, and there were 3 mini brittle stars stuck to the cuke. one fell off
but 2 made it into th ebag as freebies along with the cuke.
