I have a recently acquired red parrot that was completely bright orange-red when I brought it home a couple of weeks ago. Now, I've noticed that it appears to be turning black in some areas along its sides and even a little around its mouth. Is this natural? Should I be concerned about it?
I also have a couple of (now) larger parrots which I've had for a while and I've noticed them "digging" in the gravel on the bottom of my aquarium, by picking up small stones one at a time and releasing them onto an adjacent pile. This leaves somewhat of a crater at the bottom of the tank with a pile of gravel next to it. (I've also seen some of my other fish doing this from time to time, but the large parrots appear to be the most active at this.) Any idea why they would be doing this? Is this sort of activity very unique for fish?
thanks for your help.
