We estimate our salmon at about 170 survivors in the tank.

Holy Salmon!  We got back from Christmas break and this is what we saw!  They are not eating yet, but we will start feeding them soon.  Some still have a little yolk sac, but you almost can't see it anymore.

Below is a video of our salmon "scooting" along the bottom of our tank.  They are starting to swim up and by the time we are back from Christmas break they should be swim up fry!
