Got offered a fish from a friend, which seems very peaceful and active.
But I cannot identify which fish category it is.
At first it was very active and keep swimming to and fro, sometimes seen to be eating algae on the plants or at the bottom of the aquarium.. but since some days it look so passive, like just floating around at the top part of the aquarium.
Can someone help identify it from the attached pic?
It's shiny silver in color, with 2 fins on top.. small tail. Danio size.
