I have the Chain Loaches as well as Dario's, Kubotai's and Rostrata's and none of them are like the clowns, they all have their own little quirks but not to compete with the clowns.
As soon as I step foot in the same room as the clowns on a morning they all come to the end of the tank and go berserk, and if I dont feed them straight away they will follow me backwards and forwards along the tank until I open the lid to feed them.
Chain Loaches are fun though, always on the go and always chasing each other, very funny to watch.
