Merry Christmas to you! What a great thing to see is a belly load of eggs!!! Woot!
You will start to see little eyes. That is quite a load!
As for litlte things that suck up eggs, a couple years ago I was given a scoop of baby Albino BN plecos and the guys were teensy so I put them into the 12G Edge tank to get big enough to move, problem was, they were elusive, and I could NOT catch them Edge tank was a dumb idea for putting something easily able to hide and wiggle out of the net gaps
But they got bigger and to about adult size and I almost NEVER saw a baby, berried shrimp but not tiny babies.
I had to break down the entire tank, twas a thing of beauty and I had to rip it apart to get those vacuum baby sucking guys out of there. Afterwards, guess what - LOTS and lots of babies. So they might have been just casually sucking around the tank but BAM! Baby eaters. Similar with the baby Kuhlis I had but in a 16G shrimp tank I got them out more easily.
Shrimp production really is best accomplished as a species only tank. (I really didn't actually believe it - I am stubborn) But if babies is a side benefit of keeping the adult shrimp in a DT, they are fine with the bigger shrimp
