Baby Shrimp?

Baby shrimps are very small when they first hatch, maybe 1 or 2 mm long. Baby cherry shrimp are straw coloured not red though I do sometimes see one that is more coloured than usual. They are very difficult to see.

My water technique involves siphoning water from the tank into a light grey bucket where I can see juveniles and adults. I then use a half litre plastic jug to scoop water out of the bucket and I examine each jugful carefully for signs of 1mm long things moving on the bottom. If I see anything, or I have larger shrimp in that jugful, I then decant the water from the jug bit by bit into an empty cheesecake tub. I have a fish medicine pipette with the end cut off that I use to drop betta pellets in one by one at feeding time. If there are large shrimp in the tub, I use the pipette to remove the muck and pour the shrimp back into the tank. If there are tiny babies I use the pipette to suck them out and into another cheesecake tub with a bit of tank water in. On occasions I have found over a dozen babies this way.
Yes, it does take longer doing this than siphoning water out of both this tank and the betta's tank and refilling them both  But at least I know I get almost all the babies I siphon up.
