are those a tiny cherry's or what !!

I see a pair of adults...but it might help if you could indicate where in the picture you think you see the shrimp. Juveniles are teeny, less than a quarter of an inch, and difficult to photograph without some quality zoom...but I don't see anything in the pictures that looks like a juvenile shrimp, just the adults. Maybe that's a matter of scale?

yeah I couldnt see anything, maybe capturing a video might help if you see movement?

Newborn red cherries are tiny, barely pink, essentially invisible...except in movement. Easiest place I found to see them was up on tank walls. But if it's been 2-3 weeks since these were hatched they should be perfectly easy to see, miniature versions of the adults. If you're not seeing them either (1) they weren't there in the first place and you were seeing planaria or something or else (2) they were there in the first place and are now either hiding or dead.

Be sure that whatever you are feeding them has a good amount of calcium in it, and see if you can find a seashell or two to put in the tank (broken pieces are fine, these are chemical additives not decor. ) On the other hand do NOT feed the tank very much, just make sure you have plenty of plants on which they can graze.

I am pretty sure I killed my first 3 batches of shrimp by overfeeding them. Then I read here, took seriously the advice, and the shrimp survived and thrived and bred. They look so easy but the trick is to back off and let them live as naturally as possible.

The little blue specs? No. Those are not shrimplets...I don't know what they are, but definitely not shrimplets.

this old thread of mine will show you what to look for...
