Welcome, Jesse … nice to have you aboard.
Your CPDs will probably slow down a little when they get used to their surroundings, but they are very shy by nature. If you have hiding places in your tank, they will use them when you are near the tank.
As your white clouds get older, they may get to all of the food before your CPDs can get there. Keep an eye out for that. I just put all of my CPDs (19) in their own 20G tank last week — I was having to do some tricky things so my CPDs would get to eat in my main tank. They are not aggressive eaters, at least not when other types of fish are around.
Looking forward to you sharing some photos with us.
