I have a male and female pair of damsels, i am not sure what they are specifically but they are colored tan and cream. ( i just call them davenport). But my concern is that the larger of the two, the female, has just recently began to burrow a large hole between the bottom of two pieces of live rock. She fans away the substrate (crushed coral) and then actually picks up pieces and swims them across the tank and deposits them on the other side. i'm concerned because she digs all the way down to the tank bottom, and when i first noticed the hole i refilled it with the surrounding coral only to have her very angrily clear it back out. Then when i put my face by the tank to see her work - she gyrated very angrily at me and actually nipped me when i put my hand in the tank to readjust my powerhead. I'm pretty sure she's still mad at me :? . i dont know why she did this and i wonder if i should keep refilling the hole she dug. I heard somewhere that this could open a pocket of ammonia buried in the substrate and consequently do some real damage. Could she be getting ready to lay eggs? any input would be great --- thanks everybody. I put in the best pic i could get of her and the hole.
