Is my ghost shrimp okay?

[luvsgiraffes]

I have 3 ghost shrimp. I've had them since Sunday.
When I first got them they zoomed around the tank for a few minutes, then settled down. And then pretty much huddled in the corner farthest from the heater. I tried to turn the heater from about 75-76 down to about 72

Now there are 2 still huddled in the corner and one that has been zooming back and forth in the front of the tank for over 2 hours straight. (this is with the light, and without). I've already fed them today, and I saw him eat a whole flake of food. And his tank buddies are 5 glow light tetras that leave the shrimp alone.

Is it okay?
THanks for your help! and sorry to freak out if it is nothing

Mine do the same thing.. they have active days and lazy days-- they also love to be around the heater even when the water temp is fine

I wouldnt worry
