I have 3 Albino Corys and mine do what your new ones do..O.k. they do their bottom vacuuming bit .. but then look out away they go shooting around the tank like crazy lol.. Then it all stops and they lie on the bottom without moving.. When i first saw this thought .. something not right here..now i know different I just watch to see if they "Blink " lol cause they are so still.. Love the guys and they get along great with the zebras, Haelequins and Endlers Ohhhh and they do at times give the assissin snails shells a clean lol Regards Zac
