My gbta keeps receding into my rock at 400 every day. He stays there until around 630 and they he inflates back to normal. It's always the same time.... He never does it any other time and he hasn't moved since I placed him into the tank. Probably just because he found a hole to put his foot in. But he's at the bottom of the tank at the base of a rock. My curly q and condi don't display this activity just my bta. This being said my poor clownfish gets confused somehow every day when this happens and he goes to the curly q to try to host. The curly q only recedes until the clown goes away. Then he try to see the condi. Which in turns Stings the mess out of him and he swims around dazed..... so i digress. What's cause my bta to recede causing my clown to go on a high.
