So, all week I've been coming home to a rock with acans upside down in the sand. Each day I turn it over, ponder it a bit and go on my.

This rock of acans I moved from a different location in the tank to the spot they are currently in this past weekend.
Today I woke with it upside down in the sand, again. The acans at this point are not happy with everyday dealing with being upside down in the sand.

I turn it over and go about my business.
An hour later the acans are upside down in the sand. Again. I turn it over and sit on the couch watching the tank from the side. I watch the foxface and wrasse swim about. Then I see on the other side of the tank the toppling of the acans. Again.
These are the two other fish in the tank. These two are the culprits.
I take the rock of acans and glue it to a second rock thinking that this takes care of the issue. I sit back down on the couch and watch the tank from the other side again, pondering my recently chopped gorgonian and the two newly glued frags from it. When I see on the other side of the tank the two clowns take a larger loose rock with lots of duncans on it and topple it over the acans.
The duncans are now face first (if you will) in the sand.
Clownfish = 1; Owner = 0
That is it!
I place the rock of duncans back above the acans. I then proceed to move a bunch of sand over to the corner of the tank where the two clownfish like to keep clear of any sand whatsoever. Those of you who have clownfish know they can be stubborn on what they will and will not tolerate. For my two clowns, it is no sand near the rocks where they lay eggs. I gave up that fight long ago with them. You can see in the pic above the glass bottom of the tank, no sand.
BUT, today the sand goes back there! Now they have something else to keep them occupied and I hope they will leave the duncans and acans alone.
I now bring a chair over to the clown's side of the tank and watch them try to move all the sand out by rubbing it with their bellies to stir it up. I see that the female is ready to lay eggs. Again. No wonder the odd behavior and not liking the new spot where I placed the acans.
I am determined to win this fight!
