Recently purchased an orange King Midas from my LFS. I'm convinced he's the smartest fish in the world. If you run your fingers up and down the glass, he'll follow you. There's just one thing... He won't stop picking up multiple rocks in his mouth...He takes these rocks and dumps them in the corner. He'll pile them up until the pile reaches about 5 inches high. Although I think this is a cool thing, he's starting to become slightly discolored, and I kind of want him to stop. What should I do?
Thanks
