I've had a gold-stripped maroon clownfish for about four months and I always thought it was strange that it pretty much spends its time at the back of the tank and other than feeding times never comes out front even though it is the only fish in the tank. Now just this week it seems to have decided that it doesn't like the sand at the back of the tank and has begun to dig holes and push the sand to the front of the tank. Is this weird? Does anyone else have maroon clowns that like to move sand? Luckily, I put my supporting rocks in before the sand so I have no worries of it colapsing but the frag rocks I've added are getting covered up or are having the sand washed out from under them.
