Really? My Midas Blenny and SW mollies see me as the almighty food god. My Midas almost always starts swimming front and center if he sees me stand up. The pipefish don't really seem to care about me much either way. When I put my hand in the tank it's a different story. The mollies seem indifferent, the midas retreats to his hole and the pipefish still don't care. I'd say that as long as you aren't making sudden movements and are feeding regularly the fish will generally learn to tolerate you, depending on the species. Even jawfish, which tend to startle easily, will learn to love and praise the food god.
