I've had it for about 2 months. It never moved around much, it would stay in the same spot for days at a time. The only real drastic thing I've done with the tank lately is change to Kalk drippng from liquid suppliments in an effort to raise my calcium. I've tried to keep the drips slow to prevent ph spikes but they did occure. Are they sensitive to changes in ph? None of the other inhabitants were effected by it. Perhaps it was a dud from the start.
