Maroon clown playing in sand?

[nel621]

Lately my tomato clown has been "playing" in the sand. Every now and then he will swim around and then lower himself into the sand and kick up a small sand storm. Is this normal behavior?Is he having fun or just going nuts?

ugh my maroon does that when his anenomee gets close the sand bed... the little SOB dug all the way down to the glass (3 inches)
