I had only read about small loaches shadowing large ones but I observed this with mine for the first time the other day. The smallest loach was firmly attached the biggest one, with its nose close to the eye of the big loach as explained in this thread. It was like glued to the other loach. They normally beg for food each morning and are really excited. It was then that I observed the shadowing. I think its been reported many times by clown loach keepers. Why they do it is unknown. It's really funny though.
