If you have fish with them I doubt any will make it.
This is probably what will happen, but I have mine in a tank full of Endlers and there's always some juvies that make it. I also have a lot of moss growing in there so I'm sure that's the reason they can't all get picked off.
Here is a quick pic of some of the shrimp. I'm pretty sure I saw a small shrimp walking around he might of been in here a few weeks already but I never did see it and I know he is new because the others are very big already. I don't know where that snail came from but it's been in here a while now.
I bought a pair of ghost shrimp for fun when I first started my tank. One came berried so I was even more excited -the green eggs just looked so cool! Anyway, the eggs hatched and both shrimps died shortly after. Fast forward a month and I found one lone ghost! It is now a 'teenager' and the odd one out amongst my RCS/PFRs.
