Certainly most captive fish species that show signs of this are likely to be unwell.

fish fins are in no way comparable to cetacean fins. Fish can fan and close their fins at will because they are rayed. Drooping dorsal fins in killer whales is an individual characteristic. Even in the wild certain individuals have drooped dorsals.*
*It may also be a sign of captive problems, I don't know, but having a drooped dorsal fin is not a sign of a problem per se.
