I have a school of 7 clown loaches between 3 1/2 " to 7" and they are always playing dead, sometimes alone or in a group, I don't know whether you loaches have done this yet but they will also stand on their tails and lean upright against the sides of the tank or driftwood for long periods of time. Normal clown loach behaviour.
