Ok, this is probably a silly question. I notice Drumheller Fountain is once again partially drained for cleaning. A few weeks ago, when it was full (and filthy) I noticed several large goldfish nosing around the remains of a chair down in the murk. Now, of course, you can see clear to the bottom and the fish are not there. So, does anyone know what happens to the fish when they clean? Do they keep them somewhere and put them back? Do they release them humanely into the wild? Put them in their backyard koi pond? Obviously, nothing huge hinges on the answer to this (not even a bet), I'm just incurably curious and now this is bugging me.
