CLownfish behavior

[Dawn'sEmone]

Hi,
I have a question about my Maroon Clownfish. I have had him now for about 2 months and he is doing great. He host a large beautiful BTA which is doing great as well. They were purchased togather.
They are in a 90 gallon reef tank with 7 green chromis and 2 lawnmower blennies. All the water parimeters are normal.
My question is.. The clown scoots his tail into the sand and swishes it back and forth. He does this only in front of the BTA. He moves the sand so much that you can see the glass on the bottom of the aquarium. I will push it back and it is push away again by him just that fast.
I was wondering if anyone had an idea of why he is doing this.
Thanks

He probably is a she if it's the only one in the tank! Sounds like it could be cleaning a bit of space for eggs... but i could be wrong!!

my female clarkii does the same thing when she is looking for food, or when she wants fed. something you just kinda have to learn to live with. the hilly sand draws alot of attention to the tank its kinda nice in an "all natural" looking tank.
