I could think of 2 reasons causing eggs to drop, stress due to bad quality water or there isnt a male. What kind of shrimp is it?

Ya it is possible for the female shrimp to drop the eggs if there is no male

Why must there be male around? Is it true?
I always isolate my pregnant CRS from the rest.

You mean unfertilised eggs?

you need the male to fertilize the eggs. unfertilized eggs will *always* be dropped regardless of how little stress or how good your water conditions are.

How long was she holding the eggs for? Unfertalized eggs drop pretty quick. If the eggs were fertalized stress may be to blame (water quaility, tankmates, ect)

Hm...i thought the female will mate with the male abt 2 days before they actually produce the eggs. So the eggs you see on the female are definitely fertilised.

I always moved the pregnant CRS to a separate compartment. So far so good...have one good brood of ard 40 babies.

Thank you for all the suggestion and i tested the water today:

ammonia: 0
nitrite: 0
nitrate: safe level

and the 15G only holds 10 red cherry shrimps and 5 Japonica shrimps. I think there are 4 males red cherry in the tank. Thanks for more input!!
