my 3" H. hippopus refuses to stay where i put it. i've had it attached to a small piece of liverock that i buried in the sand to give it a solid base. it has released it's byssal threads at least 4 times and moved to a new location. this wouldn't be so bad except that two of the locations are with his byssal threads attached to the glass.
how can i keep him in one spot? lighting is more the sufficient and all the tank parameters are in check.
