So I have had my two clowns in my DT for about three weeks. All is good, they are eating well and swimming around good and getting along. I've even seen the smaller one "stand straight up and wiggle' in front of the bigger one. 
Question is, in the corner area where the tend to sleep there is a small area they made a hole about 1/4 of the depth of the sand bed. Looks to be about 2.5" around. Any reason for this? It is the area they go to every night when it's lights out. No anemone as the tank is only 4 months old. All water params seem good: PH 8.1 Ammonia 0 Nitrites 0 Nitrates @5. (WC coming this weekend) It's just a FOWLR for now.
Thanks willy0508
