It's seems my blood parrot has taken up some odd hobies. He likes to spend most of his time cuddled up against the heater. And today he has started moving all the gravel in the aquarium to the other side, one stone at a time. He dives down, and sucks up a single stone into his mouth, swims to the other side, and drops into the corner, then goes back and repeats. He seems to be very picky about which stones to move, inspecting several before deciding which ones to add to the pile.
Is he attempting to build some sort of nest?
