Sajjad,

The photos were dark on my monitor, so I can't help with the minnow.

>From your description, the larva you described is almost certainly a
member of the family Syrphidae, a family of flies. Some are aquatic
(like yours) and some are terrestrial. Most put their eggs in
organically rich locations, and the larvae eat "grunge." Aquatic forms
are sometimes, for the breathing tube on yours, called "rat-tailed
maggots." A search by that name, or by Syrphidae, or syrphid(s) will
yield more information.
