Can you identify these fish?

  • We are currently upgrading MFK. thanks! -neo
to draw them out from the corner, add decorations and some dither fish, like appropriately sized silver dollars. again, how big is the tank.
 
100 gallon, ive got some decoration in there but planning to get more, today they seem to be moving up and down the tank, they all seem to stay close with each other
