I am just wondering what they should look like as of now. None of them have any color.
Any advice is much appreciated.
I never did figure out what caused such slow growth. But there is definitely something wrong somewhere. The one thing that comes to mind is that baby brine shrimp lose a lot of nutritional value if they are allowed to get over about 24 hours old. Try adding some frozen food too. There's really no permanent harm done and if you can get them to start growing they should still get to the normal full size.
