Unfortunately the whole reason to siphon is to remove debris that has collected throughout the substrate of the tank- siphoning in just one spot defeats the purpose.
Surprisingly I have never had that issue with any of my fish.. but I bet I would freak if I did
I wouldn't remove them each time simply because then it could easily reset their whole pecking order, territory, etc.. may cause excess stress. If you are afraid of it happening again, I would trick them into one side of the tank.. if you have an extra set of hands available, have them throw in a few pieces of food on one side and you place in the siphon on the other. And just start vacuuming from that side.. once you start you shouldn't have to worry as you won't be bringing the end of the hose out of the substrate by much as you go along.
Glad to hear she is doing good.
