Fish Fanatic
Omen is my big old Jaguar cichlid, and like most cichlids do, he rearranges the gravel in his tank a lot. However, he also has half a dozen golfball-sized apple snails in there, and he's decided those are just "rocks that move". So he'll pick them all up in his mouth,one at a time, dump them in one corner or another, and chase after them to pick them up and put them BACK where he wants them. Sometimes he'll do this for 30 minutes to an hour. Then he gets really annoyed they won't stay put, whaps the whole pile with his tail, scattering them, and ignores them for a day or two before doing it again.
