rocks are moving

[xxHLTxx]

rocks on the glass bottom even with sand pushed in is still easily moved underwater by cucumbers, starfish, crabs or hermits. Ive personally seen some nassarius snails digging under the sand and they pushed a base rock almost 2" out of place.

broke 3 large acro colonies and dropped a hammer on an acan colony.

Not if you start with flat rock on the bottom and stack on the flats. Theres no room for them to get under the rock.

yesterday i walked by my tank and seen that rock had fallen down so reached in and put it back up about 45 min later 2 more rocks fallen down so the tank has been up and running for a year and had no problems tell know
i find it weird that the rocks are just falling know so any ideas that might help would be great
is there anything that could be moving the rocks ( critters ) that is

For the love of humanity, please use punctuation.
My biggest turbo snail (roughly 2 inches) has pushed over a rock (a little smaller than a baseball), but it wasn't that stable.
I always try and tip my rocks with my hand and see how sturdy it feels. If it moves at all I'll just keep moving it until it doesn't move anymore.
Good luck.

I have egg crate under my rock with sand between the rock and egg crate.
i have no turbo snails just hermits and emeralds along with the serpent star,and brittle stars.
i have been watching my tank all day looking for the culprit who done this with no luck.
i will know do a coral dip on all my rock to see if anything comes out does any one know how long
to dip my for I have read somewhere to ( dip them for up to 10 min ). Will this time hurt my corals
in any way. Thanks for your help

Revive is a good dip. Just rinse, in saltwater, all rocks and corals before adding back to display. So yes you need two buckets of saltwater before you begin, one dip and one rinse.

Just an update reefcheif called it. It is my stars doing it dam monsters they have moved all the sand out from
under the back and it has all shifted. Thanks for your help
