This started about 3 days ago...he first (with the help of my Exasperatus/ tropheops hybrid) removed gravel from under a cave of rocks to make a clear path to exit out of the rear of the cave (was too small with the gravel)
Then my Auratus (by himself) starting removing gravel towards the front of the tank in clear space.
What is going on here?
My only conclusion could be that when I feed them, I usually drop the pellets in the middle in open space and they fall where he removed gravel to have easier access to the food, but why?
