True perculas - A sand shifter?

[my pair of true percs have never been in or near the sand....nor have they ever been in their heteractis crispa :uhoh:

They rotate back and forth in their playground of torch, frogspawn, xenia and goniopora :cussing: .]
 
[It's really case by case but clownfish in general do it fairly often. From what I've heard/read maroons tend to do it most.

I have a pair of false percs who I don't think even know there is sand on the bottom and a pair of Clark's (in a different tank) where the female stirs things up all the time.

I had a female maroon in the past who dug literally everyday!]
